CurveCP seems interesting (like most of djbs work). Would you get most of its client-side benefits (mobility support etc) if you'd create VPN over CurveCP? That way you wouldn't need to install it to the destination servers, but instead use a server with a stable, fast connection as a gateway.
Or is there some neat VPN solution that has good support for mobility already?
