I remember of a quite efficient way a program on my HP48 worked to act 
as universal remote:
It encodes the stream as a succession of counter values, each of them 
being the duration of a receiving/non-receiving state. If a duration 
exceeds 256 then special value is used to code duration on more than one 
byte (thinks of UTF-8 coding style).
The result still takes some bytes, could take quite a lot of time to 
transmit with the small packets of the radio :-/
We could also have a look at the way lirc encodes learned codes and use 
directly that coding on the tux.

BTW what is the IR receiver hardware? Does it demodulates already the 
36kHz and outputs in TTL?
In other words, do we have to sample the modulation or just the 
bits/Manchester-bits?
