Hi Matt,
unfortunately, the java daemon + applet code do not share any code at
all. That's mostly because we wanted to split the daemon code so that it
could compile into an elf executable with gcj.

We should have thought about this. What the applet does is simply
calling periodacally the daemon using the commands it knows the daemon
will recognize, but there is no common file for command definitions.

I guess this should be done for gomd.

Also, as I wrote in our web page, I'd suggest using UDP for "inter-nodes
communication" it's going to be faster as well as easier with commoncpp.

Of course we could use the same port number for TCP/UDP sockets if we
choose to implement the thing this way.

I'd say, a monitoring client connects to any gomd daemon and that daemon
should be able to gather the info from the other nodes first from the
/proc interface, then falling back to UDP with other daemons for info it
cannot directly obtain from its own /proc.

I don't know... it's just an idea. I'm sorry not being able to code
much. I haven't had much time to study :( I'm having big troubles at
work trying to make two java RMI servers intercommunicate using SSL :)

Also, I've spent much time fixing the first 5 chapters of the oM HOWTO
by Kris and he said he applied all my patches! :)

While you were talking on #openmosix I was watching the "Twelve Monkeys"
movie :)

That's it. Keep up with the good job!

Ciao, mc²
