Hi -- this is an interesting issue. I've been wanting to learn more about scheduling automated tasks in Ruby on Heroku but haven't gotten there yet. My sessions tend to time out after a long period of time, so I haven't researched it thoroughly.
But that won't keep me from commenting on both, since no one else has. ;) Dave Naffis' plugin looks reasonable, it's simple, which might explain why he didn't write any test code. I would be tempted to use it, too. Sweeping the database is a good idea, maybe even sweeping sessions that were created_at more than "X time ago" to catch attackers who hijack a session and run a script to keep it from expiring. For cron-like tasks, Ilya Grigorik wrote an article: http://www.igvita.com/2007/03/29/scheduling-tasks-in-ruby-rails/ From his article, it looks like OpenWFEru is a good choice and it's a standalone gem now so quite possibly Heroku may have it available. I would be concerned with any scheduler crashing. Make sure there is some way it can be restarted automatically and a log entry created or an email notification sent so you can detect problems. Good luck!
