I was wondering, whether that is an option, or how you'd think about that.
I would imagine, using the same storage model, or at least have a bridge (importer & exporter) from one format to the other would be cool.

Distributed bug trackers are not a simple concept, and are not widely in peoples scope for tools to actually use in practice. Widening market-share by combining efforts, or at least combining the potential user-base should benefit both(/all) projects. Not to mention the sharing of brilliant minds focused on the same topics.

this issue might be a good point for initiating contact, if it does not exist yet.

... or do you see fundamental incompatibilities in the ideas behind the two projects?
