The only one I know for sure is Kevin Upthegrove who does the 5 Minutes of Rum blog/podcast. He mentioned on my Instagram post that it was unnamed at the time and that he had dubbed it "The Man with the Golden Rum" to match the spy theme of the seminar. Here's his post & podcast about that drink which has a photo of the people seated at the table (but without names mentioned in the post or audio) other than his wife, Val Upthegrove. I've interacted with Val when she started selling Tiki-themed masks this spring (also does Star Wars, Disney, Harry Potter, and punk/goth ones) on Etsy and I just ordered my 4th a day or two ago. $5 goes to charity to support the staff of a famous Tiki bar in California during the Pandemic.
