Hey Locoweed. Glad to see your tutorial made it into the contest. It would have been a shame to miss out with all the work you put into it. And you are currently leading the poplularity poles as well! Fantastic work!
By the way, I just got a chance to test Bioshere IV MP over the internet. Server side was on a MediaCom cable modem, and client side was on a UUNET 56K dialup. These two connections require 14 hops to talk to each other! I had a latency of between 192ms and 210ms and it still played great. I've played big name games that didn't play worth a crap at 200ms latency.

You BPS rate is amazingly low. I even checked your UDP packet rate, and it never got over 20! I must say this is a superb example of what can be done. I would love to see a community test with a large number of clients. Based on the numbers I'm seeing, I think it could do very well.
As far as the game play itself, animation, movement, collision detection, targeting, weapons fire, even the startup 'grace period' worked very well.
I saw a couple of anomolies on the client side, but nothing that actually interrupted game play. Absolutely fantastic job!
Hope you get rested up and come back soon.
