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.
