What I am wondering is, if hypothetically this restriction were lifted and one could set the recovery model of tempdb to Full, what would be the impact of a tempdb in Full recovery model on that hypothetical SQL Server system? Would it slow to a crawl, encounter errors, etc.?

Thanks again,

You'd defeinately see a performance hit as tempdb's log continued to grow like mad.

After all... Tempdb is the clearing house for just about everything. Order by, Group by, insert, update, delete... all of it goes through there to some degree or other. I've got databases where my t-log backups are close to a GB every 15 minutes... I'm not sure I could take t-log backups fast enough to keep the t-log file for tempdb from growing faster than backups could keep it at a reasonable size.
