Yep.  You and others keep asserting that a pull-based mapping  
distribution model is a "non-starter" because it "won't work".  I've  
been trying to get from folks _concrete_ examples of applications  
that "won't work" in the face of increased latencies on the order of  
10s or 100s of milliseconds after a cache miss.  In response I get  
vague handwaving about voice or video (I know from personal  
experience that UDP-based NFS works fine in the face of an initial  
packet delay of 10s of milliseconds) or descriptions about classes of  
applications that would appear to be degenerate cases and asymmetric  
routing that would likely have unpredictable performance  
characteristics with pull or push.

GIven the lack of data, it would seem we've descended to the realm of  
religion, so I'll give it a rest.
