I remember trying Retroshare… no offline message is the biggest obstacle.

If the firewall just means no incoming connections, your computer can still reach out to the other side (if they open their port)

I would 100% exploit this (insurance for family).

Forgot to answer this question, yes I think it would work.

Yes, speed would be much slower.

Yes, you can host a normal website through tor.

AFAIK tor websites (onion service) doesn’t require exit node, and no one knows your IP unless you are unlucky enough all nodes you connected are controlled by same entity.

I am pretty sure you can set your own DNS server in Android.

I think most up-to-date OpenWrt routers can do later (with normal, unencrypted DNS requests), see https://openwrt.org/docs/guide-user/firewall/fw3_configurations/intercept_dns.

The model you mentioned (Flint 2) is supported by OpenWrt.

route ipv6 dns to a destination of my choice

Does this mean setting custom DNS server (so devices using DHCP picks up what DNS server you want them to use) or intercept DNS requests (MITM or use firewall rule to drop outbound 53 port requests)?

My old computer that was build about 6 years ago started not getting powered since about 2 years ago, when I unplug it and took it to computer shops, that computer gets powered instantly when plugged in, but I needed to wait at least 12 hours before I attempt to plug it in again in order to make it boot (if I am lucky).

I changed the PSU, didn’t work, bought a UPS as stop gap fix, I saved money to buy a new PC instead.

There is also lowendtalk and lowendspirit, both the them are forums where you can make a post to ask.

Pick one of the address between 000000.xyz to 999999999.xyz they are sold and renewed at dirt cheap prices.

There is a game that is based on the same thinking (Universal Paperclips), you play the rule of “the AI”.
