Creating a dynamic (may be web?) relationship table/diagram between Publish/Subscribe system on Biztalk Send/Receive port

Recently, we have a user requirement that businss user would like to know the information e.g. for a certain data published to the Biztalk, which systems will be the subscriber. The information could be obtained by taking a look at the BizTalk Admin concole. However, it will be hard for business user to understand how to read it inside the administrator page.

We could make a web page and put up all information there. However, apart from inputting the information manually, is there any way we could extract such information from Biztalk? (e.g. getting from the DB? which may not be a good idea of course)
Will there be any third party tool doing that function?

Many thanks! [:)]
