Of course, not everyone is providing an Internet-wide service to provide real-time updates for anything at any time. People are going to use this to network smaller systems, in which case a less intense polling strategy would be just fine.
For example, I'm going to use it to network several personal blogs together to get content from a central publishing server, so the publishing is all internal. In this case, I may not have any "just in case" checking at all. -- Eric On Wed, Mar 10, 2010 at 6:05 PM, Jay Rossiter <[email protected]> wrote: > On 3/10/2010 1:49 PM, Bob Wyman wrote: > > We did the same thing at PubSub.com with updates that came in from FeedMesh > publishers and it worked very well.
