Hmm, it appears Tekkit is still on MC 1.2.5? Weird. Anyway, a totally uncustomized install is at finalgear.com default port (25565).
If loose_unit's server has enough oomph to work well, we could make that the main server (and I'd stop running ones on our servers), or I can give someone access to the minecraft area of our server so they can poke at it. If anyone wants to be in charge, talk to me and we'll see what I can work out. Otherwise I'll keep doing minimal work on it when people bug me or I get really bored.
