Yes, there is a 3rd party vendor which has already sold a bunch of Object Storage Targets (OSTs) to LLNL for the MCR cluster, see:
http://www.top500.org/top5/2002/11/five/ http://www.llnl.gov/linux/mcr/ http://www.bluearc.com/news/press_releases/pr_mcr_121102.shtml
These are not the "OST-on-a-disk" paradigm that we first worked on with Seagate, but rather large NAS/NFS storage servers that also implement the Lustre network protocol. We are also working with other vendors to implement Linux-based OST targets (I'm not sure whether I can reveal names or not) for even larger clusters.
Maybe if Lustre becomes popular enough, we will see Lustre implemented on single disks. There is an object-based storage group with the SCSI T10 committee, but so far their protocol is mostly unusable for Lustre.
