This has changed slightly, now.  We are able to use the "realm" concept 
and have the end-user travel to, say, ISP-B (with which end-user's ISP 
has reciprocity) and given that his login is joeblow, then he could login 
as: joeblow@isp-a and the TS would then relay to the default RADIUS 
server at which point that RADIUS server would ensure it had reciprocity 
with the "ISP-A" realm and then forward that authentication request onto 
ISP-A's RADIUS server.  After being authenticated, the TS would then 
issue an IP and accounting would be sent off to the appropriate ISP(s).
So, the only "secrets" that are shared are the md5 digest keys used 
between the RADIUS server and TS.
