Fun.  That's a way to get some more lights into your life.  I like it.

I think the only reason to have an RK11-C inlay is if you have an
RK11-C.  Otherwise I can't see that it makes much sense.

The one other place I might, maybe, possibly see one being used is along
with one of our QSICs or USICs.  I could add an option to drive an
RK11-C inlay if someone really thought that was what they wanted but the
RK11-F inlay that we came up with really is a better match and more
functional (which is why we came up with it) as well as supporting the
RP11 implementation that I'm sure I'll get working any day now (snort).
