You are probably right. HSRP could actually be used for load
balancing, as could VRRP (which is what I believe you mean by
active/active) by defining multiple standby groups per interface with
recirprocal priorities on the groups.
The same thing could be done with VRRP by using multiple virtual
routers and reversing the priorities, but then one would need a
different IP address for each of the VRIDs.

The only bright point I can offer here is that

the LVS source code has __not__ been modified.
Which really makes me annoyed, because I cannot right now see any other
obvious path (i.e. simpler).

Sorry,

After my last email, I looked at ktcpvs and realized I ignored a
couple of things: ktcpvs only supports tcp (http is obviously
tcp-based, but I thought it supported udp for other protocols). I
don't know how much work implementing udp would be.
Here is a discussion of SIP and LVS that I found useful (though
not encouraging).

Paul: I'm starting to get really curious on the standard LVS
components used for your stickiness! I'm not aware (also after
searching now) of an LVS balancing mechanism that allows correct
stickness on SIP udp...!
And I found other too who are looking for it:

My understanding is that ipvs must be extended (according to the
developer) with a call-id based scheduler and that this work has
several people willing to fund development, but that this has not(?)
started yet. The problem is that ipvs is based on ip header analysis
and extending the hashing algorithms to also include payload-based
analysis is not straight-forward.
