ok, time for a little clarification.
The links are on the cd, if I remember correctly, under the extras directory. They are basically links directly to Knuddi's how-tos on his website.
I am not sure if you understand what it takes to make the cd with all these extras. It takes about an hour. It takes longer to hunt down the rpms, then it does to add them to the ISO.
Clamav, Spamassassin, and Hylafax are currently installed using scripts. It is not as easy as adding the rpms and all will work. I believe, the last time I looked, several things are configured in the script. Until all of this is built into a rpm, just adding it in is not going to happen.
