Calculation of reciprocity, based on transaction history

Hi so sorry for the delay
I briefly looked at your paper.
There are no logical obstacles to using the mutual credit module for this.
You would need to add a field to the transaction entity for 'rating' the transaction
Then export the transactions in a format like csv or rss to input into your math engine.
You could put your math engine (and rating field) into a drupal module and you wouldn't need intermdiary formats.
Feel free to contact me directly through my drupal site profile.
