SOAP support in Acrobat Reader

Hi,

Most of our clients use the free Acrobat Reader. To a PDF Form that we develop we wish to add some web server interaction.
Acrobat Reader, we know, does not have web capture (no FDF GET, for instance). Please explain what can be accomplished with SOAP though:

From "JavaScript™ for Acrobat® API Reference:

Note: The SOAP methods connect, request and response are available only for documents open in Acrobat Pro and
Acrobat Standard and for documents with Form Export Rights open in Adobe Reader 6.0 or later.

Thanks, Enoch.
