i suggest that you just write to them and tell them that you intend to vigorously contest any attempt on their part to file the patent. see what they say. Point out the prior art discussed here already, and that while you might not object to a patent on a specific technique, and attempt by them to file a patent will be met with significant resistance. and if you don't, i will. --p
