I saw someone doing it in the logs (possibly you?) and plan to add that. Probably in the next couple of days along with some other changes to the client libraries.
Hey, if you follow the new instructions you should be able to use wildcards now. It's not in the instructions yet, and the gem is really fresh so may not be up on gemcutter yet, but if you put "*papersmith.oncloud.org" where it says to put "papersmith.oncloud.org" it should work. Give it a go and let me know if it works.
