I'm getting the infamous "Invalid (missing) src or appid" error.
I'm running this from a dev machine, and have tweaked my /etc/hosts file so my
browser thinks it's hitting the production host (www, vs. dev).

While it could be an error in constructing the uri, I'm hoping someone can tell
me if the BBAuth service would notice the discrepancy between the referer and my
IP address, or some such, and error out? BBAuth is a bit of a black box, so I'm
trying to figure out where to look for the solution...

Or, to ask the more general question, what is the best way to develop BBAuth
systems without deploying it on production servers first?

Thanks!
