But, as it stands now, even 8MB blocks might be risky at the moment
Just noticed the disconnect between your message and your username.

I appreciate your attention to details for I value that just as well.

My username suggests the next bandwidth target for the idea of a static limit on block size, but doesn't hint at the time when the adjustment needs to be made. I argued against many other more sophisticated scalability proposals with mathematical rigor, but it was when I found myself defending the future limit against the current one, that I realized the obvious contradiction in my line of thinking.
Finding the appropriate moment in time for the transition would become the most challenging and interesting part of Bitcoin's evolutionary path.
