The key point I was making is that vague statements about simple 
theoretical features are (almost) useless in a domain where it is 
absolutely critical what precise algorithms and performance the system 

There are plenty of UDP-based systems that are FAR worse than TCP in 
*every* respect, yet were specifically written for games developers from 
the ground-up (usually *by* games developers...). I've even seen some 
like this that were (apparently) commercial.

Even Sun has *failed* to correctly implement 
random-backoff-and-retransmit in a major network protocol (RMI up until 
a few years ago...). This is a company with considerable expertise in 
networking (and a brand carefully associated with networked systems...).
