Absolutely not stupid.  This is the essential VPN concept (at least in my 
mind).  There isn't any reason why the configuration that I outlined 
shouldn't work for both ends as long as the public skiphost address on 
one end is fixed.  Even better if both skiphost addresses are known in advance as 
that relieves the requirement that the skiphosts be located in-line 
through the use of static routes.

With this kind of setup you can even access the Internet from the other 
end, set up Exchange server replications and anything else you can think 
of that can run over IP.  Great for desktop to desktop transfer if you 
have enough bandwidth.

For secure systems, I prefer a screened subnet system.  The skiphost 
functions can be combined with bastion host functions running on a 
perimeter network.  I have one system with VPN nodes in USA East Coast,
USA West Coast, Belgium, Goa, India and Taiwan. Soon to add USA Southeast
and Delhi, India.  Works great.
