just a quick comment here.  i would encourage you not to do that.
Honestly, I completely agree with you that MD5'ing our OSPF adjacencies isn't
a great idea (I've so far stalled its roll-out).
Just in case it's not obvious to any onlookers here, Eric was talking about using MD5 authentication in OSPF adjacencies, and Todd is talking about using the TCP MD5 signature option (RFC2385) between BGP peers.

They are two different things (although they both involve routing protocols and the MD5 algorithm): not all arguments for or against one will apply to the other.
