Whatever terms you like. I think I understand the potential benefits of 
a push model:

Yes, exactly. I think Grok should scale up, which is why I said I 
thought it needed to support both. I think we figured out a way to do 
that at the sprint, but we'll just have to try this a bit more. The wild 
west approach seemed easiest to make progress on as it's so similar to 
ZPT, so in the interests of making progress, I wanted to focus on this 
initially.

I think we're just violently agreeing here. :)
