Thank you for your interests in our product.
You are right about IPv6 support in LiteSpeed, it is on our to do list but with low priority as IPv6 is not ready for prime time yet, and we don't know anyone using it for web hosting. Looks like we are wrong. :-)
We will try to make it available soon, as there are seperate IPv4 and IPv6 listener, it is pretty easy to do what you are asking for.
There will be new features designed for mass hosting in the next RC release, please stay tuned. :-)
