The "egg" prototype already does the above commands.

The "egg sync" stuff was to get the latest package information from  
PyPI and from your locally installed packages so that you can do fast  
and offline queries against it.  If you don't sync, you'll have to  
rescan every time; sync'ing is just an optimization, and since it  
gets put it in a little database, it makes making queries etc much  
easier as another benefit.

I haven't seen that done, but since eggs in uninstalled and installed  
form are the same, it should be easy.
