So I have flashed my Droid 4 with the following steps:
Rooted Android
Installed the latest Safestrap Recovery
Selected Safe slot
Flashed cm11->Sailfish 2.1.3.7 failed
Wiped
Flashed cm11->Sailfish 2.1.0.11->Sailfish 2.1.3.7 worked

I can confirm moodroids problem: The hotspot does not work.
I also checked everything mentioned in the first post. I can confirm most of it, except Video recording: It actually works

I see this mentioned in the thread, but maybe the post should be updated.

Bluetooth does pair, but does not work otherwise.

Wifi worked after the first reboot

Pin is curious: At first boot I entered it "Wrong Pin",
entered it again "Wrong Pin", pressed cancel and saw that the pin actually worked.
After the third boot it now still displays "Wrong Pin" but closes the pin requester a second later by itself.

And finally I have the 100% battery problem. Its horrible. I have made many reboots and its still stuck at 100%, having the phone shut of at "random" times is very bad. Also it seems like the phone doesn't charge in that state, or does it? I don't know.

Finally: Sailfish is awesome! So much more fluid than the stock rom! I love it.
