Mini to Roamio over VPN?

Any way I can get a Mini to recognize a Roamio Plus over a site-to-site VPN? The mini is already linked to the Roamio Plus on the LAN, I want to know if I can move it to another location and once there it would pick up DHCP and look for the Roamio at the same LAN IP which I can make reachable via VPN.

Assume bandwidth is apx 25 mb/s with 15-18 ms latency.

possible?
