I'll have another shot at this :)

vfs is unreleased.  I think it's pretty safe to say it should stay that 
way at least until web2 is released.

vfs' APIs are obscenely unstable.

as is web2's stream.  As James pointed hopefully stream will eventually 
move into twisted core.

fair point.  but this just means as stream's abstraction is reworked to 
meet general consensus - vfs will need to be rewritten to meet the changes.

It would be fairly straight forward to add an adapter from ivfs to 
producer/consumers if someone has a need for it.

I personally was keen to use streams with vfs as, being new project that 
has the luxury of being unstable, I wanted to pitch at were twisted was 
heading.  I was also hoping to add to web2's momentum - nevow on web2 
still feels a long way off and its something I'd really like to see.
