I'd like to thank all that have responded so far, Mr's Hill, Bruce, Doug,
Pete, Marc, et. al., Thanks much.
Analyzing Broadband Networks by Mark A. Miller, is ripe with example
traces via a 'expert sniffer internetwork analyzer', a serious little tool
top thing, I had occasion to play with one. As mentioned, not a cheap toy
for sure, yet, not 'unafordable' either...
Now, perhaps I can refine my question some here for more detail;
Do most folks here run their networks with encryption on the endpoints of
their private frame relay links?
Aside from the 'public' frame realy connections open out here on the net,
are their 'real' concerns of snooping, snatching, and or hacking via
'private' frame relay connections and your 'peers' on the far endpoint?
Again, thans all,
Ron DuFresne

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