With file based footage the offline online workflow is tricky as you will have todo a conversion from high quality to low quality which takes time.
200hrs shooting on P2 would also be a challenge i would have thought.
That footage will need to be on a big raid and probably backed up to firewire drives anyway
My feeling is your shooting with the wrong camera !
You would be better off shooting either DVC PRO 100 tape
HDCAM tape
or maybe XDCAM HD
Good luck, you will need it.
