Synchronizing two svn repositories with bzr. Is this possible?

[Josef Wolf]

Hello,

I have two subversion repositories that contain mostly the same content.
Just a couple of files are different in those repositories. Now, I'd like
to "synchronize" those repositories. That is: if a change is committed
into one of them, I'd like to merge (cherry-pick?) this commit into the
other.

With git, it is possible to specify two (or even more) remote svn
repositories and move patch sets this way. While this works, it is rather
complicated to do with git. Maybe there's a way to work against multiple
svn repositories with bazaar? Any ideas?
