select call forwarding/ enhance inbound call routing

While the inbound call routing feature is one of the best things I've seen from any voip provider, I was wondering if it could be expanded a bit to turn it in to a more user friendly version of select call forwarding?

I know, right now its select call forwarding of sorts but there isnt a good way to turn it on and off via handset or SMS so what I propose is this:

add 10 * codes for select call forwarding (*20 - *29)
On the web you assign a contact group to one of the * codes.
To forwar/unforward the group you dial the star code.
this way if you have kids or whatever when they go out they dial there code and all calls from their friends go to their celll phones.

I think this is a pretty nifty idea and a very different and user friendly way of implementing selective call forwarding.
