Hi Phillip,
You can find all you want to know at the website: http://www.eduroam.org,
especially the Service Definition at:
http://www.eduroam.org/downloads/docs/GN2-07-327v2-DS5_1_1-_eduroam_Service_Definition.pdf
you may also want to watch the cartoon at:

In short:
There is a hierarchy of RADIUS proxy-servers (institution, country,
European/APAC/Americas) that form a web of (transitive) trust.
This RADIUS infrastructure is used to forward EAP requests from the
visited institution to the home institution of the user, the home
institution of the user verifies the credentials and sends back an ACK
or NAK.
When the visited institution receives an ACK from the home institution
the user gets access.
Users connect using 802.1X with WPA2/AES
Hope this helps,
Klaas Wierenga
