Thanks Steve, that was my understanding also.

Is it also true that there are no implementations of TTLSv1?

FYI, EAP-TTLSv0 does not require any changes to the TLS handshake.
Only EAP-TTLSv1 does.

Thanks,

Yes, I reject that approach to tunnelsing.  But you could for example
use the TLS application record protocol to tunnel EAP.
