Not having read the whole thread in all its entirety per se, could you
be specific on what exactly you need proper documentation? Is it
netfilter or IPVS related, and if so, which part of LVS?

Furthermore, I'm compiling some development text while distinct
questions pop up, however I'm not going to document everything ;).
Regarding IPVS I've put online a doxygen'd documentation, which can help
significantly when trying to understand the code:
