Is this feasible?

I have some NT's at work. They run tests all night.

My boss would like to be able to dial in from home, using 
his home PC (Win98) and view the screens on each NT. I 
was thinking that I could maybe do it like this...

VNC (WinNT) -> SSH (NetBSD) -> MGETTY -> 
SSH (Win98) -> VNC (Win98)

That is, I'd like to:

1. From a Win98, dial into a modem owned by NetBSD.
2. Have mgetty answer the modem.
3. Let boss first login in the clear.
4. Boss could call a script that I would write.
5. The script would establish an SSH IP-tunnel 
   from Win98 to NetBSD through the modem.
6. Boss could (transparently, I hope) connect his
   Win98 VNC client the NT VNC server on the LAN.
   
I've gone and bought the O'Reilly book SSH. And 
everything has to do with IP connections (Internet and 
LAN). There is no mention of PPP or mgetty. 

To answer "Why?"... Things would get political were I to
suggest hooking my little four-NT LAN up with the company
intranet, much less the internet. So I was hoping to 
skirt the issue with a convoluted end run. Doable?
