That is correct. First fetching the ebuilds required, then actually merging
them.

Are there any performance issues with this approach besides network
speed/bandwidth.

And let's say I'm not on WiFi. These are mobile devices after all.

I'm thinking of a proxy server setup that could calculate dependencies on
the fly and only download those specific ebuilds.

Also, I could see GLEP 9 as being useful for updating over cellular
networks.

That would be excellent. Python's virtualenv utility is pretty neat.
It would be awesome if one could install portage inside of virtualenv, or
to be able to `pip install --user portage`.

Not sure how that would work technically.
