Re: Messenger-Esque Windows Service: How Do Major Messengers Do It?

The IETF standard for doing this kind of stuff is called XMPP:
http://www.xmpp.org
http://www.jabber.org

There are a number of .Net tools out there to let you leverage this
protocol, including full client and server SDKs.

I am fairly new to .net development. I have read a number of articles
about developing messenger applications, but they all assume that it
is operating internally and that the IP address of the client is
known. I would like to develop a messenger-esque service that will
communicate live database information to a central, remote server.

The process would be something like this:
1) A user at the remote site requests information from the messenger-
esque client
2) The remote server contacts the client
3) Client sends information
4) Remote interprets

I know this sounds like a web service would accomplish this, and it
would. However, my target users will not know how to (or care to)
install IIS and configure it appropriately to host a web service. How
do messenger services handle this? Is the client constantly
communicating with the remote server to check for requests? Any advice
on how to get started with this?

Thanks!
