This could be related to your system default font (larger than mine I 
guess). Anyway the default window size should be larger and it will be 
larger in next release. BTW, you can resize the window.

This one looks like a bug, I will check.

"-server" is an option of the java virtual machine. It should give some 
performace advantage for server-like applications. It is an 
optimization, it is not strictly required.

"org.hmedns.dade.jcgrid.cmd.povray.JCGridServer" is the name of the 
class (a file with Java code) to run (if you unzip the jcgrid.jar 
archive, you will find a file named 
org/homedns/dade/jcgrid/cmd/povray/JCGridServer.class")

The two keywords are not related.

No, it is just the name of a file (it is the java way to name packages). 
It is not related to the workstation where you run the software.

I suggest you:

- One Server on Xeon;
- Workers on all (don't forget to set JCGRID_WOKER_CPU=4 on dual xeon 
and JCGRID_WOKER_CPU=2 on dual PentiumIII);
- Clients on any host where you want to use JCGrid/POVRay for rendering.

Run a client and the rendering will be splitted among the 7 workers 
available on your grid.

Let me know if it is still unclear.
