I created a Fedora Core 6 image at:

http://docbill.info/downloads/FedoraCore6.exe

The compressed size is just under 300 MB.  The uncompressed size of the file system is 4GB.  I also included a 512MB swap.

This image is configured to use VNC, so you can connect via 127.0.0.1:1 and use Add/Remove programs to add the applications you plan on
using.

This is about as small as I can make the image, and still have the Add/Remove program available. 

I have started trying to make a smaller image, that only has YUM available, but I am beginning to think it isn't worth the effort, since the first thing people will likely do is add in the same programs...

If people are happy with the image, I can add it to the sourceforge site.
