That might be an option - AFAIK the trailer will be visiting schools, so I doubt it'll be going so far from civilisation that it can't get some sort of signal. The problem is, it needs to support anything up to 15 workstations, so I'm imagining that would reduce a 3G connection to a crawl.
As for speeds, they specified 'broadband speeds'. Technically, 512k is broadband speed, and if they have any hopes of streaming HD movies in the middle of a Welsh valley, then they've got a steep learning curve ahead! You can get 2Mb connections on satellite, but it's seriously expensive.
Still, you get what you pay for - if they really want decent BB from anywhere, they'll have to go with the satellite option!
