I think the reason the rotary has such a ridiculously small crankcase breather passage is that almost all blow-by gas gets automatically recycled into the intake ports. P Port engines may need more since this only works for side port engines.

I ran it to a small plastic bottle filled with brass wool to try and capture any oil droplets. In over 100 hours of operation, I have never seen any liquid accumulate.

I just tubed it over to the air filter box, but I've always been curious as to what others are doing with this as well, but just never bothered to ask.

My question is with regard to the ventilation of the case. it seems that the rotary has a nipple off of the filler tube for this purpose... (I don't think that I have that tube currently and will probably make one)
Using this port, is it a good idea to just plumb it out of the back of the airplane as with a crank case vent?
Is the amount of oil/vapor created significant enough to collect it and recycle it?
