Name suggestions are very welcome. :)  Now that focusedFrame() only returns
local focused frames, this is intended to be used for special cases that do need
to know about remote focused frames.  Let me know if this is kind of what you
had in mind when we discussed this last week.

This is essentially what I had in mind. I can't think of a good name either
though.
