1. Is there a way to limit number of concurrent jobs PER user ? That is - if one user started a workflow with 30 steps, Executing only one (or two or three) jobs of that user, instead of all his jobs hogging the job-queue (and causing other users' jobs to wait).

Not currently, but this feature is planned.

2. Is there a way to force users to login? Prevent un-logged in users from running jobs ?

Yes, via the 'require_login' option in universe_wsgi.ini: # Force everyone to log in (disable anonymous access) #require_login = False Which goes well with this option: # Can users register new accounts? #allow_user_creation = True Unfortunately, both are available only in the security branch right now. --nate
