Note that for VLBI for sure, and particle particle physics IMO,  
fairly high packet loss rates could easily be
accommodated with no need for retransmission, and so there is no  
reason to use TCP for these applications.

This situation cries out for some sort
of "worst than best effort" scavenger service. If anyone else feels  
the same way, we should try and arrange a Bar BOF in Philadelphia.
