I got the idea --- but I'd like to hear it straight from the horse's mouth. That is, a link to something a Boonex rep has said on the feature.

From what you describe, we're just talking about sharing a common member database across applications.

A couple of ways you can code something like that, also for shared environments where the host doesn't permit remote access. Shouldn't be that hard if someone at Boonex thinks it's important.
