There's an obscure (not well known) Slackware-based live-CD called Goblinx that may be of interest to a few. I've not tried this distribution yet, but will soon.
I'm interested in how it compares to Slax. I've used Slax off and on and even a few times at work as a rescue CD. There's also a security-oriented version (formerly Whoppix) called Whax (http://iwhax.net/): Whoppix was based off of Knoppix and Whax is based off of Slax, which is based off of Slackware...they are the same authors who developed Whoppix, but changed the distribution of use and the name of their product.
If anyone has tried both of these, I'm interested in a comparison of both and a listing of their pros and cons when in relation to each other.
Lastly, there's also Stratux. For more info (there's nothing but a torrent file on it's site), visit ##slackware or #stratux on irc.freenode.net.
