Organic Groups Invitation Autosuggest

My users wanted a feature to make it easier to find and add users to the group invitation form. I thought I had seen a request like this and maybe even a patch in the OG issue cue somewhere along the way, but I can't seem to find it. So...

The attached module is a first stab at adding an AJAX suggest-style user picker. The RealName module handles all the field setup and configuration, my little module just queries the realname table and suggest usernames based on those values.

Anyway, I'm wondering if the maintainers think this sort of thing should ship with OG or not.

Thanks.
