So then why not read the source code, get some ideas, possibly use some of
the code if it makes sense as such, and include a copy of the license and
copyright notice with your redistribution to cover your legal requirements.
Of course if the project was GPL'd, which is incompatible (as far as I know)
with the MSPL (as well as pretty much every BSD-like license), then the
clause in the license stating that the the subsequent license MUST be
compatible with the MSPL would obviously present a problem. So I guess I
can now see where you are going with this.
