I embedded it right into the library.zip of web2py by openning .egg package and using its pyamf folder. I'm quite sure that pyamf is being imported, because before I did this trick I was getting "no module named pyamf" error. I also tried using the source version (by appending it directly to app.path) with the same result. The problem is that I don't know how to debug this scenario, the browser shows error, apparently because the request lacks some stuff.
