Is there any way to embed Flash completely in HTML, without reference to an external SWF file? I ask because I would like to send an HTML file as an email attachment that the recipient will open in a browser and fill out as a form. The last step is that they will copy the result to their clipboard, paste it into a new message, and email it back. I cannot reliably copy to the clipboard with JavaScript because of the security issues, but there are simple Flash apps to add that capability.

I know I could just display the response text (which will be Base64 encoded) to the recipient and have them copy/paste, but it would be nice to provide this small convenience to them.

Also, so you are aware, the text is often too large to include in an email using mailto.

Yes. This needs to be done via email. The users have slow, occasional satellite email access and no other data connection to the interwebs. To make things worse, I cannot make them install anything. It is a difficult situation.
