I would appreciate hearing (anecdotal) reports of the costs people have
observed running tcp/ip over international x.25 networks.  I am
particularly interested in how the packet charges add up when there is
sporadic interactive use with telnet-like applications.

As background, there seem to be two ways to talk from here to there,
leased "line" and public x.25 network.  With sufficient gateway
hardware, one can run tcp/ip over either, and the choice comes down to
cost.  With a leased line you *know* what the cost will be: many
kilo-sheckels/month.  With x.25 you are traffic sensitive, both by
volume and density.  The worst case seems to be interactive login, where
it might take one (or two with echo) chargable packet per character.

Thanks,
-dB
