I could be wrong, but wasn't with the ratification of the 100Mb/s standard that the 4 byte VLAN tag was added to the Ethernet frame? I know, unrelated, that Jumbo Frames only exist at 1Gb/s and higher, but I seemed to recall something about VLANs as well.
Not to say you can't VLAN other links, but only in an untag fashion.
I agree doing MAC-based auth is a headache waiting to happen, but I have no clue what he is getting on about there.
Appletalk was certainly headed on the way out, until Apple came out with OSX Server and made filesharing happen by default via Appletalk. It's a pain in the ass, though, when your Appletalk zone fragments without you knowing it and a printer goes off the deep end... grrr.
Sounds like some book. I've never bothered with the CCNA, I just end up reading the docs or googling when I need to setup something moderately complex. Cisco annoys me to no end, but they usually make good equipment, and the CLI interface is awesome. That said, it seems like every rev of IOS, and man... there are like 40000000000000 of them, breaks the things it fixed 2 revs back. Ugh. I still have my account tagged on TAC with the Motorola global account number, so I have access to anything I wish to download. Woot. Just need some Cisco gear now... hehe.

If you want some Cisco junk to play with, I've got a nice emulator if you just want to play. Email me if you're interested.
I have no idea when VLANs became part of the standard. I know we were doing it on 100M links in class.
