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.
