Great stuff!

I just forwarded it to Alan Borning who hadn't known about your project.  He has an interest in coordinating such efforts so we don't duplicate too much in the future.  He also has some new technology to contribute to Cassowary.

It is probably time to start a conversation about merging some of the power of Cassowary with Ned Konz's fairly intimate integration with the Morphic UI.  Ideal would be if there were a preference to turn on and off simple constraints (a la Connectors), and then a package that could be filed in for more powerful constraints(a la Cass), but with essentially the same UI.
