I think the import issue is important, but so is export.

I would not start using such a system without being certain I could
recover the file view of my code any time I needed it. Moreover, a
programmer might want to combine the IDE with file orientated tools such
as an existing revision control system.

The IDE would need smooth, reliable, efficient import and export to
stand any chance of widespread adoption.
