actually
... that's kinda cool - as it stands I download out-of-copyright films (like Metropolis or Nosferatu) from the Internet Archive and stream them over my network to my PS3 - this is a bit like building that functionality right into the PS3.
Though to be fair, I'll probably continue to download it to my media centre PC and stream to my PS3 since a) once it's downloaded I can re-stream it across my network rather than hammering my ISP (and getting throttled) and b) my PS3 has 80GB drive space compared to about 1.5TB on my media centre.
