OK, I promised this a long time ago, but things have been
more than a little busy around here.

My configuration lets any host at my house access any
host at the office, but only lets the PC on my desk at
the office access hosts at my house.

I downloaded a program called "Tray Ping" that runs in
the system tray.  I run it on my home PC, and I configured
it to ping my office PC every 119 seconds.  This keeps
the VPN active continuously.  I found "Tray Ping" either
on Tucows or on ZDNet, I forget which.   Any utility that
lets you schedule pings at an interval will work.
If you have a UNIX or UNIX-like system at home, you can
easily use  cron  to schedule a ping every minute.

I also have an Excel spreadsheet that generates HEX and
ASCII random 64 bit keys (you can make longer keys by
running it more than once).  If anyone thinks this would
be useful, they can get a copy from my website:
http://mwburden.home.attbi.com/MakeKey.xls
(On the REALLY off chance that anyone is interested, my
homepage is  http://mwburden.home.attbi.com.  It's
mostly there as a place to show some photos).

Note that the random HEX string and the random ASCII
string generated by this spreadsheet are NOT equivalent.
