linux-powerpc: booting from zip disk ?

Does any one know if I can boot linux from a zip disk on a PowerMac G4 ?

Ethan Benson mailed me a script to produce a CD image so I can boot from
it and install Debian, but unfortunately I don't have access to a CD
burner anymore.

So can it be done ?
Do I need to fool around in Open Firmware ?
If so what do I need to do ?

Thanks,
Brendan Simon.
