Why would you allow outside air to enter the housing through the desiccant plug ? Isn't this the cause of your frosting, fogging issues?
You mentioned 3. that the camera is now sealed once ring is attached.
confused...
My understanding is that the housing should be completely sealed and purged of any air/moisture within.
So isn't the heater ring only a band-aid solution to the problem ?
Not a critical objection to the method, but a curious question of the processes.

I had a chat with Theo and there is a circuit board on the ring that slightly heats up the air in front of the glass nosepiece to stop any fogging. This ring can be used anywhere in the imaging train. I my case as I don't use a glass nose piece it is likely I'll fit it right before the glass of my MPCC.
Of course you still need to seal your camera and use dessicant but I can see many applications for this ring as any glass surface exposed to the cold air inside the camera can potentally dew up.
