I can't speak about the status of SIP/TCP development in Asterisk, but
I can say the following:

. I've tested Asterisk SIP/TCP and SIP/TLS against a variety of SIP
implementations (acting as SIP peers) in a lab setting and things look
okay.
. I ran into a bug when I register a SIP end-point using SIP/TCP
(http://bugs.digium.com/view.php?id=12282).
. I think some of the challenges relating to deploying Asterisk
SIP/TCP in production environments will be - connection management and
NAT traversal. I think certain design thought needs to be put in
SIP/TCP feature design to combat these issues.
