The initial goal could be to provide an installer USB image,
replicating the current install CD image functionality, and document
the boot process.

In fact dd'ing an existing ISO to a USB key may Just Work

It may involve hitting Command-Option-O-F at startup, and typing
different semi-arcane commands, but people are more likely to have a
USB stick than a writable CD

Once we have booting a writable USB image, it should be relatively
straightforward to extend than to a full live image, with a desktop,
browser and suchlike. That would make it easy to test NetBSD/macppc
without overwriting anything already installed (albeit with slower USB
disk access).
