Tuesday, April 18th, 2006>p>Pyro is an example of an application that blurs the lines between a rich application and an ajax application.
Pyro embeds WebKit on OS X (which is very easy to do, enabling these applications nicely) to offer a rich experience on top of 37 Signals Campfire chat application.
Why would you want to do this? What if you want a dock icon to bounce when a message comes in, or show you how many messages are there, or do a good job at alerting you in other ways (e.g. could intergrate with Growl). Pyro does those things that a pure web application can not.
This isn’t the first of these hybrids. Apple iTunes itself is kind of like this. A rich shell around a web engine. But iTunes doesn’t offer a pure ajax application to go with it.
