I just had a wow moment... I was not paying attention to the presentation I should be paying attention to and catching up on blog reading and found this entry by Adam Hems Link to A British Geek in Texas Pontificates : Caching in Winforms / SmartClient Apps. The interesting thing he suggests is to use the System.Web.Caching namespace on a Windows Form application to cache client data... WOW I have used the winforms namespaces in a web app in the past but I never thought to try the reverse. I can't wait to play with this.
