Yep – I will ask on wpmu as well.
But what about the buddybar question? I’ve read about how people implemented it in bbpress – but that still is in the same wordpress environment.
What about getting the buddybar on an application external to wpmu?
Can I set up a page template for a page that just spits out the buddybar html – then include that on my external subdomain either as a php include or as an iframe??
