This is an important difference between us. I say that some applications are
better suited for UDP, others for TCP or VMTP.  Since the application 
programmer understands his application the best, he should choose which 
protocol to use.  You say that NCS's beefed up UDP protocol is always the 
best, for all (or almost all) applications.  This may be true in the future.
(I doubt it, though).  It is certainly not true now.

If we ever do find a single communications protocol which is best for all 
(or almost all) applications we should call it HGP, standing for "Holy
Grail Protocol." :-)  In the meantime vendors should provide flexible RPC 
systems.
