yet another reason to switch to CentOS

Due to changes in our subscription arrangements with Red Hat, Rackspace can no longer offer Cloud customers hourly billing for RHEL licenses. Rackspace Cloud Servers customers will be billed for Red Hat Enterprise Linux (RHEL) instances on a monthly rather than hourly basis.

Rackspace will begin charging customers a $20 monthly licensing fee, starting in September.
