Hello Markus,
please use linux-can@vger.kernel.org (Cc'ed), as the berlios list is
outdated.

You can open as many sockets from as many applications to CAN as you
want (until you memory runs out) and send and receive CAN messages.

The first exemple would be the shell introspection tools to see what's
going in and out when your application will be running.

Short answer:
YES, two or more applications can share one physical interface,
using the same network interface, whether it is can0 or vcan0.
