we can already transfer many objects over a single connection with 

SPDY without SSL would be more speedy than with it.

There may be only a couple R-Ts to get an SSL handshake, but sprinkle 
on a CRL / OCSP check and you're left eating dust.

So, let's just get this straight for the record.  SSL will not improve 
latency.  It will make it worse, and for many people (on 
already-high-latency links) a LOT worse.

  Personally, I thought that the first optimization was for latency,
 How do you optimise latency by adding 3 RTs in a SSL setup?
  with bandwidth as secondary and (obviously) consequential.  Trade-offs
  may have to be made.
