-## Homework 3: Problem Prototyping
+## Homework 3: Recording OpenDIS Network Streams
 
-Freeplay opportunity!  Pick one of the provided course examples (single or multiple source files)
-and adapt it to block out a protocol of interest.
+* OpenDIS PDU Track Sender, modifying provided code
+* Result streams are recorded/saved/replayed using X3D-Edit or Wireshark.
+
+*Freeplay opportunity!*  Pick one of the provided course example programs 
+(single or multiple source files) and adapt it to demonstrate a new
+client-server handshake protocol of interest.
 
 Be sure to provide a rationale that justifies why the networking choices you made
 (TCP/UDP, unicast/multicast, etc.) are the best for the problem you are addressing.
 
-While some minimal functionality is expected, the general outline of a networking
-problem and proposed solution is of greatest interest.
+This assignment is also a Problem Prototyping opportunity.
+While some minimal functionality is expected, the general outline of
+a networking problem and proposed solution holds great interest.
+Think of it as a warmup preparation for your final project.

-Team efforts are allowed, if you choose that approach be sure to note why.
+Team efforts are allowed, though if you choose a team approach be sure to justify why.
 This is a good warmup prior to final projects. Have fun with Java networking!
