My thought was that each colony would have its own gateway - I think that is
going to be the only way you are going to get the filtering you are after,
just as each company has their own firewall. A firewall type arrangement is
effectively what you are setting up.

Then each gateway connects to a convenient ISP, be it satellite, cable or
dialup. You then arrange a convenient way of communicating your black and
white list changes between gateways. This could be as simple as an email
message to the gateway maintainers to say you have found a certain website
to be suitable or unsuitable, and they manually update their lists as
appropriate, to a fully fledged automatic update between gateways, although
this latter method could result in one community setting a site to the white
list, while another community sets the same site to the blacklist, and the
automatic update results in confusion.
