What would you want that the fast-export/imports are lacking? I think  
they are excellent tools to build some integration on.

You might want to look at my git-bzr script (http://github.com/pieter/git-bzr/tree/master 
), which I created so I could use
bazaar branches easily in git. It allows you to fetch a bzr branch,  
merge it in with your local work, and then push it out again:

	git bzr add bzr-branch ~/bazaar/something
	git bzr fetch bzr-branch
	git merge bzr/bzr-branch
	git bzr push bzr-branch

It's quite crude, but it's also only 100 lines or so and does what I  
need. It should also be simple enough to adapt it to also incorporate  
hg. When I needed the bzr integration, I looked into hg as well, but  
there wasn't a hg fast-import yet. If I understand dscho correctly,  
that exists now, so it should be easy enough to integrate that as well.
