How could I query my windows application from a we

问题:

I'm trying to figure something out regarding how I can create communication between 2 machines using the internet as the communication line.

Idea

I would like to have a windows service/application that know how to talk to a web site for the first place (that's easy) but since that time, the web site should query that machine and ask information.

Scenario

Let's imagine that I install this application on my machine, I set up where and how I have my local database and now I want to be able to use a webpage to query that database.

Protocols

I'm trying to figure it out the PPP (Point-to-Point) protocol and the idea is something that we regularly use with torrents... but I can't find any information on this under .NET

Propose

The main propose for all of this is to make it easy to persons install this application (mainly a Web Service) but to avoid teach them how to set up a domain name to point to their server, as well figuring out how to get the endpoint of the just-installed web service... I would like to "Hey, please install and set your credentials, let the configuration with me"

Is there any library that I can use to create such environment?

How about the peer-to-peer api in .net? http://msdn.microsoft.com/en-us/library/system.net.peertopeer.aspx
