I think this could well be the biggest challenge. TBH I'm thinking that a work around might be to get a few people to chip in on a one bed flat rental with WIFI, just for the purposes of having WIFI, an actual address, a washing machine, an occasional escape.

Not to live in it, just for the services.

I could just make a trip a couple of times a week to connect and download/ upload, and do some laundry!

Although the repeater idea sounds ineresting.
