Obviously that would be a very good reason to adopt IPv6, but due to 
the ever evolving hacks in IPv4 there is very little you absolutely, 
positively cannot do in IPv4. Other reasons to adopt IPv6 are that it's 
cool (I mean it - for some people this is all the reason they need), 
because it's The Right Thing To Do, to impress governments that require 
or desire it and finally, because it makes life easier in some 
respects. Personally, I love the way I can connect to a router or host 
over IPv6, completely screw up IPv4 addressing and routing and fix it 
again without fear of locking myself out.

At some point in the future when IPv6 becomes reasonably common but 
before people start to ditch IPv4, you get to multihome by connecting 
to the net over IPv4 and IPv6 through different networks. This works 
very well and doesn't have any of the scaling issues that current 
multihoming has.
