Guys, this has already been discussed in this mailing list. and I fail to see
any new element that would grant re-opening the topic.
The point is, because RFC2326 is under-specified. The server MUST support
every valid ways for a client to ping. Otherwise, it can time out live client.
IMHO, that would be worse than not timing out dead clients.
Handling GET_PARAMETER and/or PLAY would fail.
