But the transport issues, or at least the protocol patterns that are supported are still important. You'll want your new client to support at least the following three fundamental protocol patterns: 1. Messaging. The pattern that was the focus of desktop client development during the 1970's and 80's. This is the fundamental pattern of distributed processing and gave birth to email and the earliest notification systems. 2. Request/Response. Polling... A single request message followed by a single response message. This is the pattern that took all our attention during the 90's and whose adoption and deployment changed the world fundamentally. HTTP, RSS, and many client/server protocols (i.e. database access, etc) use this pattern. 3. Publish/Subscribe. A single request with multiple responses. This is the pattern that people are trying to see in RSS even though it is really Request/Response. Now, "real" publish/subscribe systems (like PubSub.com) are coming on line on the open Internet after many years of learning in enterprise and closed network use. This third protocol pattern, or "Third App" will enable entirely new applications. bob wyman
