I ran across this on ebay:
You can find the auction by searching for:BACKPACKING & CAMPING COOK STOVE FUEL CANISTER ADAPTOR
I emailed the seller and he states that it is only for a fuel cannister that is shaped like a spray paint can, and will not adapt to a standard MSR/Jet Boil/Brunton cannister.
I'm hoping that someone here on the forum has a source for the right adapter to screw into the "regular cannister" so that I can buy one and
cut and paste.
I love my Markill Titanium stove for group trips and being able to use it with a remote cannister would be perfect.
