Currently when you fill a .pdf document with forms created by Adobe Indesign CC (or Acrobat PRO DC) the just possibility to send the data is using a email client (outlook, thunderbird, ...) or sending this document in attachement of an email.

It would be interesting to using an other solution because fewer and fewer users use email client... and used an attachement is less "user friendly".

I think it would be possible to send the data using an interface or an bridge... for example a specific site (creativecloud.adobe.com ?) that would store the data directly using a URI : http://creativecloud.adobe.com/form/name_of_form?field_1=data_field_1&field_2=data_field_2&... ?

All easily customizable in Adobe Indesign. You see what I mean ?
