Well first off it's incredibly easy to get an SCA 80 SCSI hard drive that works in an octane. Those are still $40 or $50 drives all day long on eBay.

Personally I would not go for the network install because it requires knowledge outside of the installation itself. I would eventually do a network install video but I would do the CDROM one first.

Now since the Octane has two buses you could easily attach a narrow bus ZuluSCSI to the external port on the octane and place a bunch of CD images on it and use that as the CD install. Personally for the video if you were actually recording your workspace and not just the screen output having the CDROM discs themselves and the real drive would have more effect and theatrics, but if you don't actually own those I would understand.

I would do the CD install first because it is the most core, vital, understanding of the install process.

Then if you wish to explain to people how basic networking works enough to run a virtual machine that has the network install helper utilities on it, then I guess you could go ahead and do that but I would only do it after installing using discs. The disc install is the most basic and most often utilize installation, network installs where the domain of university campuses and such.

Plus the network install still requires knowledge of how the CD install would've gone, so explaining the order of opening the CDs and stuff like that is still just as important and it makes more sense if you're talking about physical media then about directories on a network.
