What is the current best bi-directional git<->bzr method?

Hi,

I'm starting to mess around with project on Launchpad which are all hosted with bzr. Short of convincing these projects to switch DVCS just for me I need a decent bi-directional way of dealing with bzr archives.

I found a script[1] which I have hacked a bit[2] to import repo's fine. However going the other way doesn't seem to work. Before I mess around too much further I though I'd check if there are any known working gateways at the moment?

Bidirectional syncing should work, though I've heard there may be some problems with multiple branches. I had a discussion with someone about the used mapping, and they hacked up something in bash, though I've never looked at it. I've lost interest in git<->bzr syncing (and bzr in general) some time ago, so I never looked at it further. What specific problem do you have?

It might be that Bazaar changed something in the last year. They change their repository format and commands quite frequently, so you might be able to get it to work with an older version.

Erm it spat out a bunch of python errors which didn't make much sense and I was hoping to avoid digging into:

*sigh* I suppose it's time to break out those debugging shoes...
