Slight extension:
I know of several companies in the content management/distribution
arena which are specifically developing various overlay protocols
(some custom/proprietary, some not) atop IP so as to better
offer/define/extend their services.
TCP is a very general protocol stack. It works well, but does not
perform as well as it might under specific loads due to overhead
and compromises made in the name of generality (eg connection
build-up/tear-down expense and latency). Writing a custom
protocol atop can be extremely attractive for these cases, and
best of all, the routers don't care -- its just more IP packets.
