Well, if it really is that hard to piece together the relevant
techniques, it seems cruel not to check in the results of your
efforts to work it out somewhere. Perhaps a README file?
On the other hand, a search turned up these two papers (which I
haven't yet read, but will):
http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.97.2397&rep=rep1&type=pdf
http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.153.6657&rep=rep1&type=pdf
On a quick scan, they both look promising in themselves, and
reference a lot of other promising-sounding papers.
