There's a couple; they're generally implemented as higher-level
libraries on top of UDP. RakNet is one
(http://www.rakkarsoft.com/). I believe Quazal also uses a similiar
scheme ("prudp" - Proprietary Reliable UDP I think is what they call
theirs). I don't know of any that actually implement a kernel-level
protocol directly over IP, but it seems that the portability you'd
lose far outweighs any benefits you might get over just building it
on top of UDP.
