Do they actually need a generic VPN?  If they only run a few 
applications you might be able to use https or similar ssl based 
connections and avoid the routing/addressing/MTU issues.  You can still 
use certificate based authentication in one or both directions if you want.

Also if the application(s) can be made to run over normal https (i.e. a 
web interface) you get the advantage of working though most existing 
proxies and firewalls, plus on the host end you have the option of 
scaling up with a load balancer that handles the ssl processing and 
reverse-proxies to a pool of backend servers.
