I’m playing with the idea of the possibility of a shared wireless network. I live in a 17-storey block of 70 flats, of concrete construction. I was wondering if it would be possible to set up a shared network, maybe across a few floors, or the whole block.

Anyone have any experience of this, either as a user or in the set-up? I’m interested in technical issues (simply expressed) and the nature of the account – can you just get a normal subscription, or given the bandwidth, do you have to get a special, expensive, one? What sort of admin/security/discipline issues arise?

All feedback gratefully received – I found one reasonably relevant article, but it is a bit on the technical side for me, and a bit old.
