I read your email with great interest, and congratulate you on your
perseverence and creativity in solving you VPN problem. However, something
occurred to me that you might want to consider.
I don't know a whole lot about Virtual PC, but if it really behaves as a
stand-alone PC which co-exists on the same LAN as the Host PC (in this case
the Mac), it should be entirely possible to set up a simple network route
which routes TCP/IP traffic between the VPN endpoint (at the virtual PC
side) over to the host Mac. This would allow you to run Apple's X server
instead of using Cygwin/X. I'm willing to bet that VPN<->VirtualPC(virtual
route)<->Max X-server is going to have better performance than
VPN<->VirtualPC(Cygwin/X).
I think WinME and WinXP have routing built-in (called Internet Connection
Sharing, or ICS). Other flavors of Windows can be setup to route using
3rd-party freeware.
