Well basicly you could use reflection to find the properties when your
loading the channel object into the application context. Theres a method
on the Type object called GetProperties

Additionally you could create a custom attribute and mark the properties
you wan't to work with.

One note on this technique tough, reflection is slow. I would implement
some kind of identitymap and store properties for specific channels there.
