Git has now support for sparse checkout. 

Testing done by Nirbheek Chauhan concluded:
> Note that this doesn't satisfy half the use of sparse trees; i.e.
> quickly fetch only a subdirectory; make changes; push. However, I
> suspect that would be extremely difficult to implement given git's
> architecture.

I think an alternate solution would be to support using the complete git checkout as /usr/portage. We'd have to rsync the caches and remaining files like herds.xml and use.local.desc then.

Confirmed to work with git-9999-r2 (next branch) as of 2014/02/22

$ git config core.sparsecheckout true
$ echo profiles > .git/info/sparse-checkout
$ echo metadata >> .git/info/sparse-checkout
$ git read-tree -m -u HEAD
$ ls
metadata  profiles
