That's only half the problem.  We also don't have a mechanism to track 
how many bytes have already been downloaded.  I will be diving into this 
shortly since the Ecogrid Client get() method is a major memory hog.   
It really needs to serialized directly to disk instead of building a 
monster giant byte[].

Alas, time to dig into the guts of axis again.
