TCP SIP and Instant Messaging

Hello,

Does anyone know when TCP SIP support will be included in Asterisk.
I amazed it isn’t already.

Also does anyone know if Instant Messaging support works in Asterisk?

The above link at voip-info notes a chan_sip patch, is this included in Asterisk yet. If not when might it be?
