Wearing my security hat...  automatically signing redirect URLs is
risky.  What if the response from the service provider is compromised?

If you're using plaintext signatures, you leak your secrets to
wherever the attacker redirects you.

If you're using HMAC or RSA, you leak signatures for whatever URL you
are redirected to.  The attacker can force you to make near-arbitrary
signed OAuth requests.

I suppose https is the obvious answer to this, since it guarantees the
response from the SP really came from the SP's servers.
