Kagu is a spin-off of ukmp. Well, it's initial steps were. Now, it's a completely different beast. Kudos for trevarthan for making the a2dp work.

I think that for the time being it would be better to continue as separate projects. Maybe further down the line it might make sense to work more closely, but for now, I think that sharing code and ideas is enough. I think that healthy (and friendly) competition is something that benefits the user even more than co-operation.
