Perhaps. I don't know if that would be enough for Eli's purposes, however.

After all, in the Grep example, it could have been invoked from one of 
the buffers belonging to the current project, or just as well from an 
"outside" buffer (because, for example, that made it easier to select 
the intended directory).
