which uses an xchan_url other than channel or profile, chanview will fail to find $a->poi and fail as there is no way to import the xchan. Instead of giving up and presenting an error, we'll send you to the requested URL anyway. If we send you with a Zid, there's a good chance you'll authenticate because xchans are like glitter - once you've got one, they get everywhere, and there's a good chance you'll know *somebody* at the hub. .
