Can't you agree to use the same subnet? You are after-all attempting to 
create a VPN. It makes sense for it to be a single homogenous subnet. This 
would provide you with a single broadcast address and allow for easy 
configuration of Samba's networking etc.

Any resolution mechanism, and Samba can use DNS too, requires a working 
resolver of some sort. You could resort to using a hosts/LMHOSTS file to 
resolve some of the machines either his services, for when you are 
disconnected, or for your local machines. Part-time networks inevitably cause 
these type of problems.
