We thought about this, and the problem with the generic solutions is that they
 tend to be active/passive. We need both sides active and fully functional all
the time, just without redundant notifications, and the failover mechanism of
bb does exactly what is needed, out of the box.

We could, given enough time and effort, implement something that would do what
we need, but management tends to be very conservative about change, and very
reluctant to allow us to spend time on anything not related to the current
projects. It's the power of inertia, and the old "If it ain't broke, don't fix
it" mentality. IOW, the bb/bbgen-3.6 combo is "good enough" to keep running.
