according to mether aka rahul sundaram from freenode? RH's stand for paid linux and support is right. it has to support who work for redhat. else you may try centos, whitebox or wbel, centos server, blah blah. or best, install rh9, upgrade it from the old repo and grab the srpms and redesign the WS or EL you like even AS. the srpms are available in the redhat ftp server. and IIRC you need to buy subscription else change the repo to dag wieers or rpm bone or livna. but i doubt if these will work with RHWS, RHEL, RHAS because the field contains rh and not centos. good luck anyway.
