Perhaps in a similar thread, is it possible to somehow SET the state
of a hint from the dialplan? Perhaps a bit like:
    Set(${ChanIsAvail(hint,234)}=Busy)
or perhaps have a pseudo-device facility where you can add it to the
end of the hint list to "hint-the-hint". Something like:

exten => 234,hint,SIP/myphone&PSEUDO/234
exten => *78,1,ChanAvailIs(PSEUDO/234,Busy)
exten => *791,ChanAvailIs(PSEUDO/234,Unknown)

This could be very useful for presence indication.
