-* Adapt the functionality for OpenDIS PDU Track Sender, modifying provided code
-* Result streams are recorded/saved/replayed using X3D-Edit or Wireshark.
+This assignment presents 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.
-*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.
+This is also a freeplay opportunity.
+ You have the option to pick one or more of the provided course example programs
+and adapt the source 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.

+## Final Course Projects 2021JulySeptember
+
+Create a dedicated subdirectory for each individual or team project.
+
+Example: `SmithJones`
+
+See the [course syllabus](../../../../MV3500NetworkedGraphicsSyllabus2021JulySeptember.pdf) for details on how to document your project.
+
+Typical final project deliverables:
+* `README.MyProject.md` providing a basic description of goals, running the project, files, etc.
+* Source code, screen shots, console text log, and any other assets
+* Powerpoint presentation, video capture (if you want)
+
+These deliverables have excellent value going forward, hopefully benefiting your thesis efforts as well. Questions welcome, keep going!
