Hmmm... I think having one cut from straight metal would be prohibitively expensive because of the gears (PITA cutting gears), but I wonder if any solid'ish chainrings could hold up to having shapes milled in 'em.

Seems to me all you need is a BCD and a CAD program to make em.... i could be wrong.
if someone knows better please enlighten me.

Well, that and a shop to do it, depending on the shop. They charge plenty of moneyz for their time, so anything you have 'em do that takes a lot of it also takes a lot of $$, which is why, imo, milling a solid chainring would be a decent compromise. Course, it may be it wouldn't be much more expensive to do it (design and gear) from a blank with a suitable CNC/machine tooling, someone who has had recent work done at an up to date shop should be able to help.

There was a guy in Japan, but I heard he was closing down. The C&V crowd can tell you about him. He made replacement Rene Hearse chainrings, amongst others, and had about 1 gazillion designs. I don't know if you'd still feel the need for custom, with that many to choose from.

I think milling chainrings from scratch would be a real pain, but I'm pretty sure you could find a solid chain ring and either etch things into it, or cut chunks out of it, "mill" it if you will. You could do a pretty dope job with a nice dremmel tool and clean it up with a nice file. I've been thinking of doing something similar to an old cottered crank where the outside chainring and the crank arm are one piece.
