Dirt cheap per GB and works as advertised. No Autotask integration but I have set up rss feeds for all of my low-end clients using Jungledisk/MySecureBackup to keep tabs on backups completed, failed, or missed.
SLOW seeding, SLOW restores, but everything ultimately works.
JD is a great starter solution, it's also very flexible because you can use the storage as a backup destination, as a mapped drive, or as a folder synch.
They are working on their reseller program to bring everything under the Rackspace brand...someday.
