Draft 3 of the RFB 4.0 protocol

That's more of a client/server feature than a protocol feature. The
protocol makes allowances to ensure that there's a clean tear down
procedure. For security reasons, if a server wishes to disconnect a
client, there's no point in asking any random client to disconnect -
just disconnect. The reason for this is that anything a client can be
directed to do can be ignored by a trojan client or a very lightweight
client.

Andrew, will there be a feature that will allow the server to drop it's
connection after a specified time of no activity?
