We currently do not support this.
We just added the ability to distribute your form as a fillable PDF form and have all of the data submitted back to FormsCentral. Your users can store and fill in the PDF form locally, then submit it when connectivity is restored. I wrote up a forum post that explains it in more detail: http://forums.adobe.com/thread/994199
Please give it a try and send us your feedback on it.
Hi Randy, Your link to the post seems to be dead. Any chance of giving it some life at all please?
