Linux Live CD: Flash preinstalled?

I need to create a Linux Live CD that has the newest version of Flash pre-installed. How can I do this or find a distro with this?

The flavor of Linux doesn’t matter, so long as I can run Flash and a web browser…

EDIT: I do not have an existing installation of Linux to work with, and I am a Linux novice...

There's a program called Remastersys that will allow you to turn your existing Ubuntu installation into a live cd. So just install Ubuntu with everything you like and use Remastersys to turn it into a live cd.

If you add the Adobe yum repo and use an appropriate kickstart file then you can build a Fedora live CD/USB image that has it included.
