Ron:

Because it's generally possible to telnet from a system back into itself, I can 
take advantage of the following (and I suspect many customers would once it's 
understood that they're being charged otherwise):

1. Signon at system MyAS400 to a dumb terminal.
2. Start a second session and issue "telnet MyAS400".
3. Once that second session shows the signon panel after telnetting, signon at 
MyAS400 a second time (actually a third time altogether but the second time 
within that session window; V5R1 TN5250e could even make this last signon 
invisible to the user).

That second session will have made two separate jobs, one job is now running 
against a virtual terminal and showing a TCP/IP address for MyAS400 because 
that's where the telnet command was run. No matter if this sequence is done 
beginning with a dumb terminal or through a ClientAccess session or whatever, 
every resulting job will show the same TCP/IP address.

Each telnet session could signon using the same "generic" profile, so every 
connection using your app would have the same IP-address/userid combination and 
your license scheme would count "1" user license in total. (Unless you're 
really counting signed-on users altogether rather than only those using your 
product???)

All that is required is any system that has telnet server and client. Could be 
the AS/400 to itself (possibly multi-homed even?), one AS/400 to another, an NT 
server running a telnet service, whatever. Every device accessed in this way 
will show the same, single IP address.
