I believe I do understand what it is you are proposing. What I find hard to understand is why you feel that you need to involve Treeleaf to do the things you mentioned. Just do them. I'm not saying Treeleaf could not be involved in some way, but you are heavy on ideas and low on experience. You seem to be implying that these are things we NEED to be doing or SHOULD be doing, but aren't. For one thing, how in the world do you know that folks aren't doing things like this already? Truth is you don't, but seem to imply otherwise. I think you would be much more effective in your words and could eventually take an important leadership role here if you have actually gone out and done some of the things you propose. You can make up fliers that direct people towards general resources on buddhism and zen, even including Treeleaf as one resource among many.
There are many ways to spread the dharma and the ideas you have discussed are merely a few of the limitless paths to doing so. We'll see what Jundo and Taigu have in mind and perhaps they are ready to involve Treeleaf more directly in the world along the lines you have suggested. However, until then I'd strongly suggest that you go out and get some experience with these matters before trying to lead others to follow. Then, you'll know much more about the realities of things like public sittings and be a leader who can inspire others.
