BIG CAVEAT!!Applying extended rights using Adobe Acrobat Pro limits you
to 500 responses as per Acrobat's EULA.If you require more than that,
you must use LiveCycle's Reader Extensions module. Simply owning a copy
of LC doesn't give you any extra permissions, it's all down to which
software product applied the
rights.http://www.adobe.com/products/eulas/pdfs/Reader_Extension_Policy_A10-5-31-2011.pdf
