This could be easily done via a script on, or somewhere
like that.  A simple invocation of 'mkhybrid' with the Right(TM) options
would create a nicely bootable ISO image.  Perhaps a cross-compiled 
installboot for alpha could be used to make the image bootable for that
platform also.  Sparc would be trickier because it needs a disklabel at
the very beginning of the CD, and a FFS partition in addition to the
ISO9660.  I don't know about any of the other platforms NetBSD supports.

I have i386, sparc, mac68k, alpha, next68k, and vax.  In theory they could
all be bootable from a CD, though I am not completely sure about next68k
and vax.  (whether the firmware supports it)  Older i386 machines certainly
can't boot, though I not sure about older Macs.

This would be a very nice feature.  I would prefer to see individual
ISO images by platform though, in addition to the "overall" CD image.
This would be nice so someone doesn't need to download 640MB when all
they want is the <100MB they would need for one arch, and source.
