4.1.1p3 is already in experimental. In order to upload 4.1.1p2 to experimental, we would have to version it as 4.1.1p3+actually4.1.1p2 by Debian policy. (As opposed to bumping the epoch, which is now discouraged.)

What is wrong with uploading 4.1.1p2 directly to Debian unstable, and then uploading pynac again to force a rebuild? I don't think anything else depends on these.
