What about using opensocial templates inside of the head section to say, set the title?
<head> <script type="text/os-data" xmlns:os="http://ns.opensocial.org/2008/markup "> <os:ViewerRequest key="viewer"/> </script> <title> <script type="text/os-template" xmlns:os=" http://ns.opensocial.org/2008/markup";> Gadget for ${viewer.name.formatted} </script> </title> </head> This does seem like an edge case though..
