Hardly far-fetched, since it was done in a commercial computer several
years ago.  The original IBM PC Jr had a wireless keyboard that used
infrared signals.  They eventually punted it because it didn't work
too well.  Input would be missed because someone would walk between
the keyboard and the PC, and it could get confusing with multiple
machines in the same room.

Wireless communication is pretty noisy and error prone.  It is well
suited to low-bandwidth applications such as telegraphy, or less
error-sensitive applications such as voice.  For applications such as
terminal I/O integrity is important, so you would need an
error-detecting protocol between the PC and the device.
