I thought the default login and password for Slackware Live was just root with a blank password. Plus, it tells you right at boot time what it is.
I have had ZERO luck with the SuSE Live Eval. I think it pretty much sucks
I have a Slackware Live CD that I really like though.
You can use 'slax copy2ram=all eject' at boot if you want it to eject it when it's done. It copies everything to a RAM drive like this.
Not sure about TT fonts
