Morphing into MIG

When we last left off, we were able to cook up a service name of our choosing, and resolve it from a client. If we hooked up launchd stuff, we could also make it demand-launch (maybe that’s for another day). But we didn’t actually do anything with that resolution. There are several reasons for that, first, because actually crafting a message and sending/receiving it was covered by a prior article. But even more than that, there are actually a substantial number of design decisions around this task, and plowing ahead requires a lot of text.

I’ll start with the previous server/client, and flesh it out in small steps. In between the steps, I’ll outline design decisions, maybe some history, and pitfalls/sharp edges to be aware of.
