Steve,
Exactly, this is where I have been heading, wondering how secure and
comfortable folks feel with private frame relay connections, do they fear
intrusion or snarfing of packets from the provate cloud, do they encrypt
such traffic to enhance the feeling of secure, has anyone encountered an
intrusion or attempted intrusion/scarfing or private info from such a
link?
Thanks,
Ron DuFresne

OK, so you're a Ph.D. Just don't touch anything.
