  Windows has essentially zero configuration for this.

  TBH, I wouldn't recommend authenticating machines to Eduroam.  It's *much* better to authenticate people.

  Plus, you can specify an NAI like "user at domain" for people.  You can't really do that for hosts.

  It's possible.  But, the ore unusual your configuration, the less likely it is to work everywhere.

  Don't re-write User-Names in a proxy.  It will break EAP.
