It's scary to think what might happen if Nexus suddenly has some sort of Real Life crisis and simply can't keep the services he offers currently afloat. Same with Fnordia.
IMHo, although they are amazing (*hugs Nexus*), the survival of a community should not have to rely solely on the generosity of one or two individuals.
I think one way to alleviate a lot of the burden in terms of BW (on Nexus' end anyway) is to make everything downloaded via BitTorrent as the only possible download option (with the FU server itself being a permanent seed for everything).
The lobby server isn't taking up a whole lot of bandiwdth (long streams of text? easy) but again, the question here is long term sustainability.
I know its a bit of a kooky suggestion (and has been every time it has been offered) but a p2p matchmaking service with supernodes might be the best way to go about this in the far future if Spring lobby ever goes beyond, say, 900-person mark.
Alternatively, we could just make it *very very* easy for people to host their own matchmaking servers.
Summary
Achieve gradual decentralization in terms of resource usage to maintain long-term sustainability by
- Permitting current lobby/matchmaking services to be offered by more individuals (easy-install matchmaking server etc)
Moving all content downloads to a BitTorrent or other distributed transfer method
