ANTS wraps the jnodeos so an application should rarely have to deal with
jnodeos classes.

This happens automatically in ANTS, the classes that make up a protocol
are run through a hash to create a unique identifier that is placed
in the header of the packets for that protocol.  ANTS then uses the
jnodeos to create a `flow' (a unix like process) for each protocol and
then all packets with the unique identifier are dispatched to this flow
where they are handled.  Currently, the resources for these flows are
predetermined and there is no real path to configure them...

I believe something like this has been done by the PANDA people if you
want to check them out.
