Thanks to everyone who has answered. As soon as I read the first 
sentence in Max's reply I realized the issue, and I might now have 
reconsidered my "problem" as a "no problem" :-)

For almost 10 years I've heard discussions about the successor to IPv4, 
but from my point of view (may differ from others..) not much has 
happened. Of course, I can imagine that when the wheel starts rolling 
for real things might change quickly. 3 years may prove to be correct, 
but are there any clear signs pointing in this direction?
