This has been haunting me for months now, but I have finally implemented working library code, and an application around the AppServer/AppClient system. The application is the couple DaMon/Probe (I'm looking for more generic names for these applications):

• Probe is an AppServer accepting AppClients to connect. It can currently supply the uptime and load average values;
• DaMon is an AppClient, asking the Session on which port to find the "Probe" service, and then connecting to it (both remotely if specified via the environment).

I have a lot of other stuff to do now unfortunately, so further work on these may be put on hold for at least a week.
