You mean for an RPC mechanism ?
Isn't Invoke() working already ? I have a JSON RPC implemention on my list,
and thought to use Invoke() for that.

There is an OnAllowResource event, after the authentication. One of the
parameters is the operation: GET, PUT etc.
If you set the 'allow' to false, you'll get a 403, 'Forbidden'.
It's not yet committed, because I wanted that together with the business processor component,
which will make implementing all kinds of events simpler.
There are stilll several improvements waiting to be tested and committed.
