Actually, the project plant does need to come from the same vendor within a country. That would start everybody out at as close to the same quality and starting point that you can get. For both previous projects, all US members ordered from the same vendor and all Canadian members ordered from the same vendor.
From the very beginning of the projects, I've said that we need to agree on a particular plant at a particular vendor.
There will be future projects, if for any reason, somebody now participating decides they no longer want to be involved in this one
We're hoping that doesn't happen but to be realistic, there's a very good chance that we won't finish the project with the same amount of people we had when we started
In a perfect world, this would be a much simpler task...
