My users have reported a problem which only occurs in OS X 10.5 (Leopard) and renders the app completely useless. Is there a company which offers on-demand remote GUI access to machines running Mac OS X 10.5? More broadly, is there a company which offers remote access to a variety of operating systems and platforms for performing one-off configuration testing? If my problem had been on say Fedora core 8, I could fire up an Amazon EC2 AMI and be done with it for a few bucks, but since it's Mac, the cheapest legal solution I've found is a Mac mini, clocking in at over $500. Maybe my google-fu is just weak today."
