Adding IPv6 support to a project like this is usually a trivial thing
to do, nothing special. IMHO the cause of the lack of this feature in
many projects is the lack of requirement. Nobody tells the developers
that IPv6 support is needed. So, not a big deal.

I am not quite sure, that adding IPv6 is trivial:
- Few years ago I had a look at squid about IPv6 support - difficult.
- Adding IPv6 support to LVS - extremely complex.
- Adding IPv6 support to snort - took almost 2 years!
If the networking code is unreadable, or using int as a storage for IP
address, then you are out of luck - better to change other software...

Hello,
A somewhat similar can be achived using relayd, but this kind of
load balancing shouldn't be done on L2/L3 level. This kind of load
balancing should be done on Layer7 with some application level load
balancers. That way you can also do more then this (like sanitizing
the requests before they get to the actual servers).
Some projects exists out there to do this, like pound[1], or also
nginx has some features for this propose, and even apache2.2 is
being extended into this direction.
Most of these projects don't have IPv6 support, whil pf has IPv6
support builtin. We are using pf for load balancing HTTP for more
than a years now, successfully.
