Sorry to be late to the party, but somehow I missed this thread.

gphoto2 is the one thing I really want on my n800.

I'll spend this weekend trying, and report back.

A couple of people reported problems trying to use gphoto2 on a Linksys NSLU2. I got it working with very little problem, but it was an older version of gphoto2 (2.1.6) and didn't do everything I wanted it to. I used the OpenSlug firmware, which has gphoto2 as a precompiled package.
