It seems blu-ray burners are available for computers including RW versions (meaning read-writable blu-ray disks). However the blank disks are $25-50 per disk, rather pricey.
An example is the "Sony BWU200S DVD+/-RW Blu-ray Disc Serial ATA (SATA) Drive" ... the drive itself is pricey.
It would appear sometime real soon now the prices will fall and it appears as that happens we'll have a different option for semi-archival that is more suitable for modern data needs.
