ok ill try to explain this as best as possible.
Rom Manager support would be useless.
for you to flash and install CWM without using odin - except you have to have root in order to flash cwm via rom manager, how are you getting that on the newest update? right by flashing cwm via odin and then using it to root.
to download roms - in order for you to download roms you need to have devs who wrote a javascript file to point rom manager to the location/names of your roms. if you dont have anyone doing that... well then you arent downloaidng any roms.
cwm is a hacked up build since koush never bothered to work with the samsung style of how things are done, on newer high end samsung devices (and a lot of midrange) its done more of teh AOSP format and thus has support, this is not one of those phones. we tried to get cwm made official in fact sugilatin even approached koush and found a way to fix it all, and was denied.
ergo there is no speeding up, you guys will never be part of cwm officially. the only benefit it would offer is then it could detect the phone and pop up so people would stop bricking their phones. which rom manager isnt at fault for, people click flash recovery and pick a device willy nilly and claim its their phone...
you want to download roms on the go have your devs apply at goo.im to host their roms there
