Lightstreamer for Instant Messaging

Hi,

I need to develop a custom IM solution, and I've been reading about HTTP streaming aka Comet, and would like to use the technology in my solution.

I have been playing around with the .NET Adapters SDK, and it seems to me that Lightstreamer is optimal for streaming the same data to multiple people (stock lists, chat rooms), but maybe not so much for streaming unique data to each individual.

I could be way off base though, so in your estimation is Lightstreamer a good solution for IM?

Hi Eric,

Yes, Lightstreamer is perfect for streaming specific data to individual users. To do that, each user will subscribe to their own unique items. Furthermore, the Metadata Adapter can enforce the user/item association, so that a user cannot subscribe to the items destined to another user.

Please let us know if you need further information.

Thanks for the quick response, Alessandro. I was thinking that would be the way to do it, to have each user subscribe to their own item.

A very simple example of an IM, with full source code, is now distributed together with Lightstreamer Server v.3.5. Open the welcome page of your Lightsreamer Server installation and scroll down to "Basic Instant Messenger Demo".
