Thanks for the replies.  Addressing the questions/issues brought up by
both of you...

There is no firewall at home.  (Well that's not quite true.  The PC has
ZoneAlarm on it but I have/will turn that off for VNC testing purposes.)

I'm not sure whether my boss would "know" whether the corporate firewall
supports ssh.  He might, but he's not here today.  What "non-generic"
stuff do you guys need to know about our corporate firewall to help you
help me?

Thanks

TO make a connection between to firewalled computers there are only
two methods that I know of:

1.  use a proxy or pass through service, there are a few of theese out
there but they do cost money.

2.  modify either firewall.  This one is important in order to get vnc
to work it is very likely that you only need to change one firewall.  
If your boss is uncomfortable perhaps you could change your home
firewall. ***

***What jerry is saying is that some connections may be blocked in an
outbound direction.  (Un)fortunatley? many corporate firewalls are
only inbound blocking.  Many that I have come across will allow you to
run any protocol (e.g. as long as your computer is initiating the
connection.

I am not sure what the situation is in your case.
