I am troubleshooting potential issues on a WiMax system.  Typically we have
the FR server on a LAN link but some customers have WAN links.   My thought
is disconnects on a re-auth session causing outages.

It shouldn't cause issues - but you will observe the latency (as well
clients when authenticating).

Most EAP timers are on the order of seconds, not sub-second. Just be aware
of the various timers, and don't tune them aggressively.

Obviously if you can co-locate a RADIUS server with the NAS, this is
preferable. Clearly not possible for eduroam, but if you have the option.

What kind of deployment are you doing?
