Before we start proposing things blindly it would be useful to know what we are talking about. Could we ask Nemein to provide a breakdown of resources utilised per service (current as well as trends), ideally also broken down by platform? I mean things like what is the peak bandwidth requirements of repository.maemo.org, how much filesystem space it uses, how many CPU cycles the autobuilders eat and so on.
Also, we really need to get a clear answer on how long the Nokia repositories will stay alive and what happens after that (eg can we have a licence to mirror them elsewhere?), because without that content we're dead and there's no point discussing anything else.
