Morgan Bath received a very good response back from Sun regarding whether we may use NIO for the SCJD project. Here it is:
The prohibition against using NIO is very recent. If it was issued after
you downloaded your assignment instructions, you are free to use NIO. If it
was issued before you downloaded your assignment instructions,
you'll know because the prohibition will be explicitly mentioned in your
instructions. Search the HTML document for "NIO".
As a general rule, no matter what you read on the web:
1) If it's in your instructions, you have to do it.
2) If it's not in your instructions, you don't have to do it.
So, you can use NIO unless your assignment instructions explicitly prohibit it. Thanks to Sun for such a quick and clear response. Thanks to Morgan for asking the question.
The response actually goes beyond the NIO issue and establishes a very helpful general rule. It's nice to know all the requirments we have to follow are to be found in the assignment instructions and nowhere else. Of course, that's the way it should be, but it's still very good to see it confirmed by Sun.

I've received a response back from Sun saying the same:
We recently changed the assignment rules to explicitly forbid the use of
NIO and the other APIs you saw mentioned on JavaRanch. However, this change
is not retroactive. If your assignment HTML document does not explicitly
forbid the use of NIO, you are free to use it.
So it looks good for those of us that have already done work using NIO.
