re: Archiving - blu-ray burner for Mac pro

hi all,
some time ago i saw a post that someone was going to get an internal burner for a macbook (pro?) - walter biscardi, i think.

Has anybody got some info on whether it is worth buying one now?
... and use it with FCS2?

I'm supposed to put together an archive of probably way above 200 hours and don't want to dump it all on hard drives or downgrade it to tape.

I'm shooting mostly on 720 24p both on 32gig cards and on the 160gig firestore, so archiving (and perhaps later authoring) on an internal blu-ray burner would be great.
