Adobe AIR deployment at login window Lion/Mountain Lion

Hi.

We used to deploy Adobe Air on Snow Leopard at login window using

launchctl bsexec `ps auwwx |grep [l]oginwindow | awk '{ print $2 }'` ${PATHTOAIRINSTALLER} -silent -eulaAccepted

This worked fine but broke with 10.7 and is still broken with 10.8. We appreciate Apple increasing security, especially with regards to applications running at login window, but I wonder whether someone has already found a workaround?

Chris from Adobe appears to confirm our observations.

Any suggestions? (And please don't propose to temporarily login a "build" user. :D )
