[GTALUG] Emulating a USB keyboard using ???

The problem is that you don't get much other I/O on these.  No other
USB, no ethernet, no RS232-style serial port.  So yes, they could
emulate a keyboard but then it would be hard to provide input to the
Pi.

The various I/O pins could be harnessed but to me that would multiply
the complexity of a project.

(A project that would amuse me, but not enough to do it, would be to
build a KM switch (i.e. a Keyboard / Video / Mouse switch without the
video part).  But that would take n gadget interfaces.)
