Thanks for the interest. A few questions out of curiousity... What kind of
server components would one need to run an adobe flex application, and if
there are fees for licenses, ballpark what is someone looking at? Same
question for development environment, what do you use/recommend, and how much
does it cost? Would flex use the Grouper API or hit the database tables
