I thought I read that Netflix was required to issue a disk as opposed to making this a firmware/software issue because of some sort of licensing agreement between the two companies.
Could be total bunk, but I think it's something to do with legalities as opposed to technical limitations.
Many of you probably know this already, but FWIW, PlayOn by Media Mall already allows streaming of Netflix to the PS3 through software that is installed on a networked PC in the same network as the PS3. Quality via PlayOn is hit and miss though, especially on a big screen.
