The good news is that I managed to grab a copy of all the pictures I'd taken, after some panicking as I couldn't find the share listed. (13-character limitation of smbclient. Pfft. Accessing the share directly worked.)
The bad news is that apparently, I won't be able to access the Internet from my room in Tokyo Kenshu Center. My phone can do e-mail, though, and there'll probably be a small computer room there. =) If I'm really nice, maybe the company will let me plug in my laptop occasionally.
