Mark Prentice of the .NET Compact Framework team has just posted an introduction on how you will be able to work with the WCF-over-email solution that will come out as part of v3.5 of the .NET CF.

Although I can’t see Steve getting all enthusiastic about using Sync Services across this binding, I think there is a huge potential here for organisations to start leaveraging their investment in Outlook/Exchange by building peer-to-peer messaging based applications.
