This means using rad-hardened kit at looking at a fairly short component lifetime; hardened, erm, hardware tends to lag about n years behind state-of-the-art (or off-the-shelf), for a reasonable value of n. I think Ted's suggestion (ie, get a big player to build it for you - ideally for the marketing value, but probably for a huge sack of cash) seems to be the best approach here. -- jan grant, ILRT, University of Bristol. http://www.ilrt.bris.ac.uk/ Tel +44(0)117 9287088 Fax +44 (0)117 9287112 RFC822 jan.grant@bris.ac.uk YKYBPTMRogueW... you try to move diagonally in vi.
