Not that far off.

S-A = win2k
OS-B = nt4

Out of the 36 different OS for OS-C and Other-OS, I can enumerate:
Windows 95
Windows 98
Windows 98se
Windows Me
Windows XP
MacOs pre OS8.6
MacOs pre-OS X
MacOs X
Linux
FreeBSD
Solaris 7
Solaris 8
UnixWare
HP/UX
different flavors of OS/400 w/TCP/IP
..
..

Not to mention that on lots of networks I had to work on, 6 to 7
protocols on the wire are common, given the basic 5 found all the time:
IP
IPX
AT Ph II
Decnet
SNA

Although I agree that we do need more host people involved, the fact of
the matter is that the network administrator is the one that sees the
big picture, given the fact that the AS/400 guys don't talk to the
Macintosh guys that don't talk to the Windows guys. TE is not only about
IP. Stuff like DLSW+ and proprietary video protocols come to mind.
