I am implementing a design where my layer would sit between client and server, and whatever objects i get from server, i would wrap it in a transparent proxy and give to the client, that way i can keep a track of what changed in the object, so when saving it back, i would only send changed information.

I looked at castle dynamic proxy, linfu, although they can generate a proxy type, but they cant take existing objects and wrap them instead.

Wondering if its possible to do with these frameworks, or if there any other frameworks that enable this...
