I'm really interested in how binder was picked. It seems like a dead
technology (hasn't been touched in 3 years according to

I think the best option is to write a layer over D-Bus that implements
the binder API. I don't think that would be too difficult since D-Bus
does IPC, binder does IPC, and the differences should be worked out with
a layer between the two. D-Bus seems like the best solution since it has
the best community backing..

Yes... I'm refraining from doing more cleanups because it seems like a
lost cause.

Do you have a msm branch someplace that is strictly msm support with
absolutely no generic changes mixed in?

The only thing in staging that is less controversial from my perspective
is ram_console.c that could actually be cleaned up and possibly merged.
