Actually, whether or not to upgrade is not the quandary. We have loaded Fedora Core 15 onto a virtual machine. Both major desktops - Gnome and KDE - are resource hogs. We are not prepared to upgrade the Penguin Farm hardware as of yet. We are looking at XFCE as our desktop-of-choice, due to its simplicity and speed.
We realize that the big issue we are facing is old news in the Linux world, since Fedora Core 8 is not supported any longer. The big issue is the use of DCOP calls in SPOCS. They appear in the Brain module, and the Speech module. D-BUS began to appear in Fedora Core 8. The DCOP service was disabled in FC9, or more precisely, KDE 4.0.
We could move to a newer version of Fedora (E.G. 15), and try installing KDE 3.5. Assuming it worked, it would be a solution. However, we don't want to impose on Fedora users; we want SPOCS to work on Fedora as it comes, out of the box.
So - the Speech module looks poised for a rewrite. We can do the Brain module later.
