16. Future Directions In Web Service Devices Cross-subnet discovery Cross-Internet discovery Roaming devices Service and client presence Roaming camera demo

17. The Future: Cross Subnet Discovery Now: Directed discovery in Windows Vista Install Web Services device by name Future: Enterprise discovery proxy Browse for PCs, people and Web Services devices across entire organization Faster response than NETBios

18. The Future: Cross Internet Discovery Scenario: A user wants to connect to and print to a printer across the Internet Trans Network Roaming Discovery Proxy and PNRP allows cross internet resolution Based on WS-Discovery PNRP name resolved by local Discovery Proxy to remote resource

19. The Future: Roaming Devices Scenario: A user on vacation sends photos from a hotspot to his family’s home PC Trans Network Roaming Discovery Proxy Tracks devices and clients as they move across the Internet Based on WS-Discovery

20. The Future: Presence Scenario: A client uses a service on an intermittent connected device Discovery Proxy hosts device presence events WS-Eventing subscriptions for device presence Limited network traffic Unicast heartbeat Low power Device sets heartbeat interval
