Hi Lon,
I don't know of anyone who has used multiple switches with the same
instance, but I don't see a problem with it. Moreover you could run
multiple Liverpie instances with a single shared config file, if
you'd like.
If the load balanced webapps share the same cookie, then Liverpie
will work. All it does is to pass back the cookie it receives from a
given webapp. Some webapps change the cookie at each request;
Liverpie is fine with that.
