That depends on your definition of "can't get away from". Your users can live on a IPv6 only lan and have the IPv4 world available to them. IPv6 supports 4 in 6 - ie you can embed IPv4 addresses in IPv6, so all you need is a gateway that translates IPv4 to IPv6 for them.

I've done it. At a conference, to unsuspecting users. All phones support IPv6 well, so they didn't notice. Not one complaint - I was blown away by how well it all worked.

It was done because some noisy attendees insisted on being assigned routable IP addresses. That can be difficult to provide with IPv4 for obvious reasons, whereas ISP's will happily hand you thousands of billions of IP{v6 routable addresses, for free.

I set up the gateway myself, rolling my own using a linux box I had lying around. Adding the 4 in 6 capabilities is maybe an hours work on top of all the other setup you have to do on the box, and that includes googling to find what tools you need and how to configure them. It's not hard.
