I have had our corporate laptop folks work on my laptop remotely.
Believe it or not, I can dial in (actually direct connect via cable modem) to MR scanners, CT scanners and x-ray equipments remotely from my home office, view files, analyze files, download images with artifacts and make some minor software changes. Can't scan or shoot x-rays...wouldn't want to. This comes in handy when I'm on call on evenings and weekends and it's an area that's 250 miles by 250 miles. I have actually been able to diagnose problems with supercon magnets that have reached a critical stage, contacted the customer and have them resolve the issue before the supercon magnet quenched and became an 18,000 pound lump of steel.
