Taking a list of pkgs, resolving out all of their deps then calculating
installed size (not calculating vs an existing install, but raw
installed size) shouldn't take too much code at all. I'll see what I can
hack up today.

It won't take into account overlaid files (like docs and manpages, nor
multilib binaries) but it should give you a pretty good upper range
(sort of).
