With encryption, a major downfall isn't being discussed. The time required to process the encryptions (encrypting, decrypting) and managing the keys would require a far higher end computer than what is required now for servers. An encryption less than 128 bit is (as far as my view) useless, because it can be cracked inside and out on your average computer. So taking into consideration having a standard 128bit RSA encryption, having a standard 16 players on a server, each player sending atleast 20 packets per second, that is already 320 decryptions that must be done on separate keys, and it must be done fast enough that the server can reencrypt the data to send back to the client, and not produce noticeable lag (god forbid that you cable/dsl players get anything more than 50ms, the world is going to end). Unless someone wants to make a port of the server and the mods to some massive sgi mainframe, using the suggested encryption scheme would not be feasable for the majority of servers out there. -- leming
