Vnccam fetches images as quickly as it can from a webcam that uses HTTP, such as the Axis webcams. It performs minimal processing, such as rotating and overlaying text, and makes the frames available via the VNC protocol (also known as the Remote Framebuffer protocol) and can optionally save them as jpeg files. It works with both Windows and Unix VNC clients.
Gnome VFS, bonobo, Nautilus, USB, etc...?
I've heard tale of a Gnome VFS plugin to let users
of (for instance) Nautilus access their digital
cameras like any other file system. I have a
PowerShot S20, and LOVE gphoto -- much better than
the crap they ship with the camera. Being able to
access it from a regular file browser would make
even nicer, especially if I can write a little
script to notice when I plug in my camera, and
automatically make nautilus show me the thumbnails...
