assuming you can generate enough entropy between requests, that should 
probably work.

note that you can only have as many players as there are bits in the seed 
before it starts to break down (on disconnect you could re-choose seed 
contributors; or rotate between players). i doubt that will be an issue for 
most games though =)

in the case of 2 players, one side could wait for the contributed bits and 
then match it with their own to produce a desired result. it would get a bit 
harder as the number of players increase, but still feasible.

any local input to the random number generator creates some weakness.

it's a question of how much and if you care.

p.s. i remember the same "common seed, local generation" mechanism on a mac 
game called "robowars"
