It would seem that you could use the TCP keepalive function for this in this day 
and age.  Are there specific places where TCP keepalive is not available and so 
you are using data instead?  I understand that there are potentially some broken 
clients that are taking idle time to mean lost contact.

This would seem like a good thing to have as optional to allow these kinds of 
applications to be used with minimal bandwidth use.
