Alan,
You can write all command line arguments to a response file, and pass this
response file to NAnt using the @ option.
To redirect stdout and stderr, you need to use the Process class.
For an example on how to do this, look at the source of NAnt's
ExternalProgramBase.cs:

Ok, I get a PathTooLongException. Another limitation of using it this way is
that the max path size is something ridiculous like 260 characters, where as
the system max path size is much larger! On top of that, I do not see a way to
retrieve the standard out or standard error from the program.
