If you want quick authenticated trustworthy entropy via TLS, just ask a widely 
used server which has PFS implemented via ECDHE_ECDSA, and uses a known CA for 
signing the certificates (e.g. Google).  The entropy you can extract and trust 
is the ECDSA signature entropy, because if they mess *that* one up, they will 
expose their key.
