Doesn't Firestone use some variation on that?

Sort of like that, except they use barrels. It is something you can see if you tour the brewery. Had the dba that was all from the Union on tap there, good stuff.

No sweat.

Was I correctly recalling that the Zymurgy Burton union was your gadget?

Yes, it is more or less the same as the one you posted.  I prefer to think it was an independent idea, but it is totally possible I saw the BYO one when it came out and it was in my subconscious when I designed mine.

Don't you know there are no original ideas left out there?

I thought I designed a wicked tap for mini-kegs only to find similar plans on-line, too.  I suppose it was confirmation that I was on the right track.

Oh well, at least my memory is not going on me.
