Problem:

An External resource which I have no control over delivers data via TCP/IP.
In addition, there are files delivered to specific folder locations on the
network.

There is a very poorly written system ("server") that uses Sockets to
intercept the data that comes in via TCP/IP and I/O to pick up the files that
are delivered. The system that delivers the data via TCP/IP knows what IP
address and port to connect to in order to push the data down to the existing
"server" that is running. This "server" must be replaced by a more stable and
better system.

Ultimately what must happen is the data must be intercepted and delivered to
other processes (whatever processes that wish to subscribe to receiving the
data).

How could this be accomplished using WCF? To intercept the TCP/IP stream as
well as the physical files and publish them to subscribing processes?
