EAP-PEAP/TLS will allow some user name/password authentication. But! the password must be stored in either plain text or NT encryption format in your database of users. If you are setting up eduroam, you only have to care about the password of your own users only, so handling a certificate may not be a problem (you don't have to manage guests). If you plan to offer a service for guests, 802.1x may be too much and you should look at a captive portal solution. But still using Radius as backend authentication.
