I remember researching this too, and remember that we actually put a 10/8 address in the public DNS. AFAIK it is not considered good practice.
I also remember a comment by one of my colleagues that the typical VPN software should also be able to handle this issue. Once you have a secure tunnel into your corporate network, you should be able to use the (single) DNS on your intranet.
