Also look at using something like raknet for the network code as it works on its own threads away from blitz, so won't clog up your client side.
B3Ds biggest limitation, in terms of client side is surface and bone count. If you have 20 bones for your character, what happens when 20 players go killing a hive of 30 monsters, thats 1000 bones that blitz has to keep track of, which will probably kill blitz.
A city with 100 people on screen = 2000 bones.
Unless you use MD2, but then you have more problems in terms of equipment attachment...etc.
