This is something that I found out today from the Kerio "Customer Service" Dept in California. I called their phone # and talked to a young lady in that department. When I mentioned that I knew that they were discontinuing either "Tech Support" etc at the end of Dec, 2005 she informed me that they WOULD be continuing Tech support for K.P.F. until the end of year 2006. I am considering going to this firewall as my Z.A. Pro subscription is about to lapse. Just thought I would pass this info on in case anyone was interested.
Edit: I later called their "Tech Support" Dept who said that the Tech support provided until the end of the year 2006 would be via E-Mail Only!
