Interestingly enough, after writing about Level 5 Routing for Web Services this morning, I happened to have lunch with Craig Burton.  Craig has started a company called JanusLogix this is doing something along those lines.  Craig calls it the application services automation layer.  Lot's of protocol heavy stuff (which won't surprise anyone who knows Craig).  I'm hoping Craig will get some additional white papers and other information on the JanusLogix web site soon, because what he's up to sounds like interesting stuff.
