Thanks!

Does this really need docker, if it’s all in-browser? Ultimately, is it just served as files from your self-hosted server and the client browser does the magic?

Yep. It’s on the TODO list…

You can do that? On ordinary, non-rooted Android?

I use Nebula. It’s lightweight, well-engineered and fully under your control. But you do need a computer with a fixed IP and accessible port. (E.g. a cheap VPS)

You can also use “managed nebula” if you want to enjoy the same risk of the control point of your network depending on a new business ;-)

Tailscale is great. The principle concern to me is that your super easy mesh network depends on Tailscale so if they want it they have control, and if they change their pricing or options you depend on them, and though they can’t see the data you send they can see the topology of your network and where all your computers/devices are.

I use Nebula, which is more work to set up and doesn’t have some of the features, not But if you slap the ‘lighthouse’ (administrating node) on a cheap VPS it works great. And it has some advantages. But Nebula also troubles me: though it’s fully open source and fully in your control, the documentation isn’t great. Instead, you can now get “managed nebula”, which puts you in the same problem as Tailscale: the company sees and controls your network topology. I fear the company (Defined Networking) is trying to push things that way. Even their android app you can’t fully configure unless you use their ‘managed’ service.

For now, Nebula is great, and my preferred mesh network (I looked into all the main ones). And for Tailscale you can run the administration server yourself with Headscale and be fully in your control.

Actually I wish Tailscale the best as a profitable business. They’ve created a fantastic service and system. But for me, I’d rather my network be in my own hands and for my own eyes. And, as is OP’s main point, once they have enough dependent users, the service might turn much worse.

I think that’s because both work on Android by being a VPN, and the system can’t handle doing two vpns simultaneously

Kind of. That improves your backup safety, but doesn’t mitigate all the risks. E.g. if you accidentally delete everything from your backup directory, then all those deletions also happen on the sync’d one.

It’s a crisis for who will support you in your old age. Capitalism or no capitalism, if you want to keep eating after you stop working, either you store enough literal food in your barn, or somebody else works so you eat.

Traditionally, that’s family: your children. Capital/investments/savings, or socialised care, spreads that around the State a bit more (or round the local or global community). But when there are few children and many adults, later there are few working people and many retirees wanting to enjoy life - and you’re one of the retirees.

It’s a “problem for capitalism” because so many people have invested in capitalism for their retirement, and that could be upended. And because actually-small investments were made, on the basis that constant economic growth means lots will be returned when the time comes.

But it’s a “problem for humanity” - all the people who don’t have children to care for them and rely on money and financial investments - which both just represent a stake in someone else’s work - for the future.

I’ve written myself into a corner a bit here. Few working adults to many retirees is always going to be difficult, no matter your economic/political system. But logically from my, simplified, argument, the last two paragraphs beckon a third. To recap,

1. Retirement funds: a stake in “Capitalism”, to provide for your retirement based on broad economic growth

2. Money: a stake in the total economy, to provide from people’s work. Then:

3. A stake in the community, based on being a member of the community. E.g. a citizen - then this is socialism. If there are enough working adults - or bread in the barn - to provide for all the elderly, then all the elderly (you included) are provided for, regardless of whether they have children or saved money or made investments.

But still, if there isn’t enough for everyone, everyone suffers. And it’s rare to find a community that really wants to care for its elders well, putting in the effort for them rather than people spending on themselves, without outsourcing to ‘capitalism’ and economic growth.
