Installing UAE on an existing Linux and configuring is a matter of minutes. Getting it on a Live CD that everybody can use is a different matter. I have neither time nor resources to do this all by myself atm.
But now that you've mentioned it I see an EAB distro in the near future.
It could be based on one of those ultra slick Linux distros like SliTaz
- tiny, about 100MB
- install to ramdisk, extremely fast and convenient
- boot in seconds
- support modern hardware
