However, some users will sit outside of our firewall, and only have ...

I have been building a client / server app with Silverlight, web services, and polling. Apparently I missed the whole Duplex Communication thing when I was first researching this subject.

I have little experience with silverlight development still but with the potential of silverlight (office 2010 live) and similar adobe air apps are there any reasons for not building your business apps for web using silverlight.

I'm using PRISM (and thus the MVVM pattern). I've got a complex DateTime picker view with radio buttons. The user can pick today, yesterday, a date, a week of a year, etc. I use radio buttons for the different choices. What's the best way to do that in MVVM? I really can't think of a clean way. I could create lots of custom behaviors ...
