It's now been 4 months since this thread was opened - and there was no ETA, we are now getting very close to the estimated time when IPv4 will run out (August) and it worries me that you have no plans to develop your network to meet the needs of your clients to expand..
I love KnownHost, and have only been with you recently, however your lack of preparation & communication for this scares me.. The part that scares me is that it "seems" that you are not doing anything and when you do eventually run out of IP's, your just going to rush in the IPv6 solution.. Disaster!
Please put my mind to rest.
