I saw on a screen cast that version PBAS version 4.5 will allow CentOS 6 for the Management node. Do you know if it will support 64 bit ? Is 4.5 still on track for a Q3 or Q4 release ? Will the upgrade on the Management node from CentOS 5 to 6 be easy ? With the current version (PBAS 4.3.3) - is any other Operating system supported or only CentOS/Redhat for management node ?
