I am having exactly the same issue.  I am currently solving it with a 
different hack that nobody likes, I will not even describe it here.  But 
total agreement that the problem is important.

IPv6 is the ultimate answer, provided there is a reasonably smooth 
transition.  I think we will need to support a tenant that is using both 
v4 and v6 during his transition.  This will require NAT between a tenant's 
v4 and v6.
