Thanks David for the clear writeup. In case anyone would like to better understand how business people will be able to 'roll their own' corporate application, please either contact the Serena website (serena.com) or send me an email. I would be happy to provide you with more details. The way to look at our technology is to combine the best practices from SOA, Web 2.0, and BPM into a single easy to use solution.

Cheers,
Eddy
