All,
	re the question `Are CD-ROMs the best method of distributing the
PUPS archive of PDP-11 UNIX material'? The answer is: it's a good method, for
the following reasons:

	+ you can't easily write over the CD-ROM
	+ impervious to magnetic fields
	+ the PUPS archive is always going to be changing, as I find and
	  add new stuff to it.
	+ the SCO license enforces that I get written permission before I
	  pass anything to a third party. Taking this in a conservative
	  fashion, this might rule out a password-protected ftp archive.
	  However, I'll check with Dion at SCO on this.
	+ we can only charge fees for copying and distribution, and cannot
	  make money on the CD-ROMs

Therefore, treat the archive CD-ROM like you would the FreeBSD or Linux
distributions on CD-ROM: they will go out of date, but you can purchase
new versions of the CD-ROM, and they should be relatively inexpensive.

Ok, so CD-ROMs are not the _best_ method of distributing the archive, but
they are a _good_ way of doing so.

Ciao,
	Warren

I still miss the distinction between CD-ROMs and WORMs.  CD-ROMs are
relatively expensive in small quantities, not just because of the
setup costs, but also because of the wastage involved.  WORMs
(writeable CD-ROMs) are probably a better choice for the anticipated
volume.

Sorry, my fault. I use CD-ROM to mean anything which can be read in a CD-ROM
drive. That obviously includes CD-W, which is what I really mean here.

I'd say at least 100 initially, and at least 300 in the first 12 months.
I'm trying to organise a bunch of people who can burn CDs, to keep the
individual workload down.

I'll be creating a Rock Ridge image using mkisofs from the archive here.
People who are prepared to burn CDs can either download the image, or the
entire archive. For the latter, I'll include a makefile to build the CD image.

Oviously, people who do mirror the archive:

	+ will be asked to burn CDs, and will do so,
	+ must be covered by a license. I will need either a signed
	  letter (on paper) describing the license, or a PGP-signed
	  email describing the license, before I can give access to
	  the archive.

Does this sound reasonable, everyone?

As I mentioned before, I can cut tapes, but not burn CDs.  I think
this is still a valuable service.

Right.  Any further news about when this could happen?

Modulo my point above, yes.

 Apologies again, Greg. Yes cutting tapes will also be valuable,
 esp. for people who have a PDP-11.

> Right.  Any further news about when this could happen?

 No, I'm waiting on feedback from Dion. He did say he had started the
 process of making it a product, but I don't have an ETA for it at the
 moment.

 Many thanks again for volunteering!!
