We found a company relatively near us here called West Coast Metal Buildings that builds shelters that look a bit like what we would like. (Such as, say, this one.) However, we didn't try contacting them over the holiday, and Lisa is uneasy trying to negotiate with them unless I'm here. The prices they have up on sample buildings outside their facility don't seem unreasonable, but the cost of something we actually want may be more than we can afford.
Lisa sent me over to her father's house so I could check my mail, but I was also to be useful, by taking her newly purchased 250GB hard drive and the one she got a few days ago, connecting them to one of my two laptops on USB 2.0 connections (her T30 has only the older, slower USB), and copying all of the files from the old drive onto the newer one. That took nearly an hour even so.
Lisa does have a PCMCIA card with a USB 2.0 connection on it, but PC cards make her nervous, due to the part that sticks out of the computer looking way too much like a lever that could break off the computer's board inside. What she'd prefer is a PC card extension, whereby you could plug a card into the PCMCIA slot and run a cable out to an external connection for additional PC cards. I figured there must be something like that out there, given that USB external multi-port hubs are common, but we've not found one in stores, and my Google-fu has failed me on trying to find such a thing.
