You could have a special sequence of characters that wouldn't normally 
be used, like \1\1\2\3\1\2\4,
and if the server receives this, you can use pyHook or something to 
generate a keypress on the other end.
It seems to me that the function keys would have a value too.
I don't have time to investigate the matter further currently, I'll try 
to look into it later.
