I just downloaded the latest version of ROM Manager and to my surprise there is a menu option to flash the latest version of SPRecovery. You cannot use ROM Manger to backup and restore stuff from the program using SBRecovery but it is still a nice convenience to have a menu driven interface to switch from SB to Clockwork. Last night an option was also added to fix system permissions. ROM Manager is progressing quite nicely (although I still prefer to flash and backup the old fashioned way).
