Are there any Indie Hackers podcast guests or interviewees you'd like to do an "office hours" session with?

Roman Vialard (the YAMM interview). I’d like to ask him about the mechanics of creating a freemium/paid Google add on. (e.g. monitoring/dealing with usage caps, sign-up process, linking their account to the add on — do they receive a key that is passed with each request/saved in browser storage?). Walking through the customers experience (install, try, signup, use as a paying customer) with an explanation of what is going on within his application on the backend. Also...any particularly difficult areas of developing/managing this type of product. Thanks!
