Scrypt and X11 have now been added to the cloud.  We're still invite only for a few more weeks while we sort out deployment environment, so please send a PM for an invite.  With the recent drop in BTC prices, you can lease an Antminer S3 for 6 months for just under $750USD. 

Currently available: 9 Antminer S3s
                           1-2 Jupiter based KNC rigs (these get a lot of rentals)
                           1 A1 based scrypt miner
                           1 6 card 290x X11 miner

100% uptime guarantee, any downtime will be compensated with additional hashes/lease extension.
