GIF (oops) ?

I have no plans currently to support other formats. At the moment, if
you want another format, you can use a command line tool such as the
fine (and free) ImageMagick tools (www.imagemagick.org) to convert to
those formats, among many others.

be run on any PC, right?

Absolutely. It can be run on any platform it can be compiled on, as a
matter of fact.

remote, it's always in "listen" mode so as not to disturb any existing
session, right ?  But why for local it isn't in "listen" ?

It connects *once* as a shared session, grabs the screen, and then
disconnects.

Listen mode is separate from disturbing existing sessions; with all VNC
clients, listen mode allows the server to initiate the connection,
instead of the viewer (useful for security and firewalls). This mode
otherwise behaves just like normal sessions; i.e. if the viewer is not
requesting a shared session it'll disconnect any existing sessions.

Note, by the way, that most VNC servers have an option to reject shared
sessions when a viewer is already connected; while useful for security,
this will break vncsnapshot.
