Has anyone else been thinking about an open network for AI agents?

Half-baked thought, bear with me. Most agents right now live inside one platform. OpenAI's GPTs talk to OpenAI stuff. Anthropic to Anthropic. They don't really talk across the wall, and there's no shared way for one agent to find another that does something useful. I keep getting stuck on what an open version would actually look like. Closer to DNS than an app store. Anyone runs a registry. Anyone registers an agent. To make it work you'd need some hard stuff figured out: a way to prove an agent is alive, a way to prove it's running the code it claims, reputation built on real interactions instead of self-reported stars, and some payment rail that lets agents send each other fractions of a cent. Concrete version. I ask my little local model some rocket science equation. It can't solve it, it's too small for that kind of math. But it's good at talking to me, summarizing, and figuring out what I'm actually asking. So it hits the network, finds a specialist agent that's genuinely good at the math, pays it a few cents, comes back with the answer. My personal model stays small and stays mine. The hard parts get farmed out to whoever specializes in them. Bigger version, same shape: a research agent finds a scraper on its own, pays it $0.003, hands the output to a translator, all while I'm asleep. Whether that's amazing or horrifying I honestly don't know. So: is this dumb? Is someone already quietly building it?
