Address metadata and Transaction Filters

Question

Is there a way to store key-value pairs for some addresses and that information being retrievable from inside a transaction filter?

We found useful the verifypermission callback.

Would be quite useful to have a general form to store values and verify them calling a callback.In fact we have some requirements for that functionality.

Regards,

There is a new feature called variables that exactly does this, it is now in testing and should be available soon.
