The "exec" module has two configuration items specifying where to take 
the input from and output to. You will want to do this:

exec myprogram {
   wait = yes
   program = "/path/to/your/program %{Some-Argument}"
   input_pairs = request
   output_pairs = config
}

Then put the module in the authorize section:

authorize {
   preprocess
   files
   # ..others
   myprogram
}

There may be other ways of doing this. In particular, you might be able 
in the users file to do this (haven't tested it):

DEFAULT	Pool-Name := `%{exec:/path/to/program args}`
	Fall-Through = yes/no

You can't compare against config items in the "users" file, but should 
not need to
