I have to disagree
Having a main server that hosts one big (or a bunch of small) servers (like League of Legends, World of Warcraft) will be expensive (eventually, if it gets big). I don't know why people would have connection problems, but it can be repaired by opening a port or by not hosting from a Wi-fi laptop. Bitfighter happens to be very light and can be ran on almost everything very well (my RPi can host a server with 6 people without lag on Wi-fi).
What we can do is easy though: we can take your idea, but make it community driven, as in host a good server (dedicated computer, no Wi-fi, open port) and have lots of levels on it. This will insure that the server is top-notch. We could have a few people host servers and we would have a collection of great servers.
Normally we have connection problems in BBBs etc since bitfighter.org is a Vps, thus not very good at hosting game servers, and it already hosts a bunch of stuff at the same time too (Master Server,
http://bitfighter.org). But if we have a dedicated computer (virtually any computer, for example, a Raspberry Pi, or a Pentium 4) will do a great job.
I am actually thinking of making my old computer a Bitfighter server
