Thanks for the support. I had similar concerns and I attempted to contact weirdbeard and yaba several days ago but I was unable to get either of their ears. Because the time is ticking on RW I decided to just put it out there and see. I'm hopeful that land 1.5 comes out prior to the 14 days this would take to pass but it's going to take the time it takes.
Even if this fails (or passes and is not possible), what I'm really hoping for is to spark some new ideas about how we manage the card supply in the future.
Nice to see your proposal too!
