You can use NetBIOS over TCP/IP (using some kind of encryption if you choose), or if you have Cisco routers at either end connected to the internet, you can use DLSw+ to form peers between those two routers to tunnel the NetBIOS across any IP network (LAN/WAN, etc) which allows Layer 2 acknowledgements to be preserved (you may need to tweak the NetBIOS timers in DLSw+ if there is alot of latency over the internet between the two DLSw+ peers).
