John,

I am not sure which software implements the 2 tone variety other than 
the Olivia Aid program?

It occurred to me after posting this that maybe the 2 tone variety of 
RTTYM might be the best candidate as a comparison with RTTY.

The RTTYM mode uses a similar 5 bit character set so would be 
considerably faster than Olivia although at some loss of sensitivity. 
Still in theory I would think it would work better than RTTY?
