If I am not mistaken, you never wrote something beyond messages like "this 
needs to be implemented". It is probably in a similar spirit, but quite 
powerful and general, and easily extensible. It e.g. can correlate general 
observables, with a time resolution that decreases logarithmically when lag 
times increase. We spend quite some time in its developement :-). It can also 
be used to calculate dynamic structure factor and similar quantities...

Cheers
Stefan
