We use dbhub at our LANparty as our direct connect server software of choice. I am the first to admit that it has gone stale upstream, but feature wise its still ahead of the alternatives on Linux or Windows.
The sourceforge project page has sort of fallen to pieces and my attempts to contact anyone involved have failed. So I have taken the latest tarball (which is up to date with CVS on sourceforge) then dumped it in to git on github. From there I have applied some patches from Gentoo, imported a .spec file I found (and disclaim) and I have created some rudimentary debian package control files.
I welcome people forking and improving things, I have been able to compile dbhub on both i386 and amd64, Gentoo claims to be compiling on PPC and others. The dbhub project has provided in the past .ikpg's for openwrt which are mips architecture - so I suspect its portable enough. Check it out at github.com/djzort/dbhub.
