I was wondering recently if it is possible to derive a protocol from an interface declaration?

I have been using NSObject -forwardingTargetForSelector to implement Obj-C style multiple inheiritance.
In this case it is useful to have a protocol for the forwarding target that the base class can inherit.
In most cases though only an interface will be available.

May be that my approach is wanting here.
