It seems there are some ways to tie Shotgun authentication into other systems for installed clients, but it would be awesome if there was some sort of hook for us hosted users.
In particular, I am very interested in a method for the current user to be transmitted, tamper-proof, to 3rd party sites that are either linked to from Shotgun, or embedded as URL panels.
An OAuth API would perform admirably for this purpose.
Cheers,
