I had seen a preprint of the new SLN paper. To be honest, I haven't had a chance to go back to my parser and see how it maps to the new paper (as compared to the original publications). The new thing has kind of an "SLN can do anything" feel to it, which it maybe can.
Having played around with SLN for a bit now, I kind of like it. Re: Tripos, open source, and Knime They definitely have a set of nodes for Knime that people can (or will be able to) buy. Those are not open source, though they have contributed some non-chemistry nodes to knime (for example the python-scripting node). They also are working heavily with eclipse and have a product (or potential product) built on top of it. I have heard some mixed messages from them about how much (if anything) they plan to open source. It will be very interesting to see how that all shakes out. -greg
