Heh, most of these threads concern sneaker net. Think of it, getting on a rocket, blasting off into orbit, chasing down the ISS to deliver a stripped down usb drive? That's just nuts. What we're talking about here is simply information. And then when uploading it is proposed, there's no bandwidth to upload it??? You're kidding right? Is there a 1200 baud modem in the corner of the ISS that handles all the data needs?? Please... Orbiter and said add ons could easily be uploaded to the ISS. The hard part is probably for the residents to find time to play with it... that is if they're pilots. Most of the time the ISS is manned by non-pilot scientists. In any case... It'd personally love to see Orbiter running on one of those lappys hangin' off the wall. I'd be quite a tribute to the guy who's poured alot of energy Orbiter, and he definitely deserves the recognition.
