You will need LiveCycle Forms ES2 not the whole ES2 suite. This will
allow you to render your forms in real time and merge XML data onto the
templates before handing them to the user. The submission is treated
liek any other web page so calling teh .Net aspx is not an issue. You
can choose to send back name value pairs or XML data. Acrobat users can
send back the PDF or if they are Reader users then you will have to also
look at Reader Extensions to allow this functionality.Paul
