I can't help but be reminded of the on-line argument I had over emergency CD-ROM's and viruses. It was stated (not by me): "If it were to infect an unprotected computer in a nuclear medicine camera gantry, it could lead to crushing and killing a patient, so you should think long and hard before you boldly insert any outside data into your workstation." I certainly DO NOT think this is what happened here.
I guess we will have to wait for more information.
In the meantime, it might be wise to kick the side of any similar device before getting into it.
