Yes, taking chunks and sharemaps out simplifies the download code a lot.  Those 
two things were the two most complicated things about the BlockWrangler code.

Someone should probably just write Yet Another Download Engine, keeping one eye 
on BlockWrangler as they do so.  At least three people understand BlockWrangler 
well enough to learn from it when implementing YADE: me, Tschechow, Icepick.
