well, i think this is up for debate... I think, were upload.module were 
to become more of an "attach" module - that did the central hooks for 
attaching other nodes ...

I think it should remain node-type per major mimetype - since there is a 
fair bit of diversion between how each of the files can be / are handled.

This definitely should get done... it's along with the whole "private 
files aren't really private" issue as well. Not to mention that 
performance of "private" files is fairly bad (i.e. it would be nice to 
avoid DRUPAL_BOOTSTRAP_FULL to fetch a private image).

yep, lots of fun and exciting room to grow here.
