Hi John (or anyone that tried -or better : managed- to do it),
A little question :
Is it possible to make a multi-row HDR panorama ? I 've mastered (I think !?) the method for doing multi-row full 360x180 panorama, and I would like to try a HDR one.
What are the headlines for doing so ?
Of course, first is bracket shooting, but then ?
Can I assemble multiple rows in PF, and then use "New Image -> Clone for HDR" ? How does PF know which row I will clone ? Do I have to do rows in separate projects ?

Yes, it is possible to make a multi-row HDR panorama with The Panorama Factory. I believe that it has already been done successfully by at least one other user. I have not done it myself, so my answers are somewhat "theoretical", but I hope this will help you work out the process.
You should not need to make separate projects for the rows. You should be able to do it in a single project.
For a three row panorama, you would use the "Clone for HDR" command four times--once for each row and then one last time for the multi-row stitch.
The Panorama Factory clones the last image shown in the upper list of thumbnails. It clones everything from the stitched image to the final image (which might be a cropped, resized or sharpened image). So you can control which image is cloned by dragging it to the end of the thumbnail list.
Here is one sequence of steps you might try.
1. Follow the standard instructions for multi-row stitching with the 0EV images. This will produce a final, fully stitched image at 0EV and also three intermediate, 90-degree rotated row images at 0EV.
2. Move the 90-degree rotated image of the first row to the end of the thumbnails list.
3. Select the +EV images for the first row and clone the 90-degree rotated image.
4. Select the -EV images for the first row and clone the 90-degree rotated image.
5. Repeat steps 2, 3 and 4 for the second and third rows.
6. Move the 0EV final multi-row image to the end of the thumbnails list.
7. Select the +EV 90-degree rotated images and clone the final multi-row image.
8. Repeat step 7 for the -EV 90-degree rotated images.
This procedure should produce three, fully stitched images at 0EV, +EV and -EV.
But as I have said, I have not done this myself and I cannot promise that there are no errors in my procedure. :-/ Please give it a try and post your experience back to this thread. If you find errors in my procedure, pleast let me know.

Thank you John (for this nice and quick answer),
I will try this as soon as I will have shooted. I will keep you informed, and if successfull, add picture in gallery .
What was a mystery for me (and you explained it perfectly) was how PF choose the row to clone : the last of source images. Simple.
