I dont think that what I want is opportunistic ipsec..

taking an extreme example, I can set up the ipsec tunnels with 
esp-null for *.5001 and 5001.* (and that's how I'm able to
trigger quick mode in my experiment).

But I want each 5-tuple to/from 5001 to get its own SPI. That
is not happening in my case. 

If I used OE, I would *never* get a per-5-tuple SPI, right?
(I can give this a try later today but the rfc definition of OE is
not what I have in mind- I really want PFP, not OE).

yes, the rfc's permit this, I'm not sure how to set up my 
SPD for this though.
