Bitbucket mirror all repositories in project.

[Oskar Granlund]

I'm writing a serverside plugin for bitbucket. My company wants to mirror some of their bitbucket projects to other bitbucket instances. My strategy is to build a project hook which has the option to mirror the whole project with all it's repo's to the other bitbucket instance.
I seem to find a lot about repository hooks but nothing on hooks at project level. Have anyone done something similar? Is this possible?
