If you only need this identifier for use in the implementation of the server, a much better way to identify players is by their Protocol object. On the other hand, if you do need to pass this identifier over the wire, then I agree with Jean-Paul that a small incremental or random number would be good.
This is what I do:
usersByID = {} # userID:user object idRange = range(1,1001) # Arbitrary limit...
def getNextUserID(): return list(set(idRange) - set(usersByID))[0]
When a user connects, I get the next available ID. If usersByID looks like:
{1:User1, 2:User2, 5:User5}
The next ID returned will be 3. I do this so I can keep reusing my IDs instead of infinitely incrementing them.
