I'm working my way through issues with putting a Netgear FVS318 VPN router behind another shared router to connect to a remote office. Lots of people say you can't do it, Netgear says you can, but I'm waiting on the proof. In any case, with a hardware-based device, they really like to have either a static IP address on each side or a fully qualified domain name (FQDN) aka DynDNS (and some router manufacturers are pretty picky about who they partner with for DNS services).
Just pointing out some obstacles to be overcome, you will certainly want to test your potential environment in as close to a remote environment as you can before you go overseas. Client (software) based VPN clients seem to be more forgiving, but as you note, you would need one for each device, unless you can work it out that one device has the VPN client on it and all of the network sharing happens through that device. Again...test, test, test.
