Since there's a lot of apps that support Growl, and only a handful have been updated yet, I'd like to know if there's a way to convert those Growl notifications into Notification Centre notifications.
e.g. some kind of add-on for Growl or a 'proxy' of sorts so that the notifications all come through ML's Notification Centre.

Sure is.
Hiss is an app that takes the place of Growl to catch Growl notifications and reroute them to the Notification Center.
One limitation of Hiss, however, is it displays all notifications as coming from Growl, rather than the application that actually generated them.
