Sounds about right. I guess the market economics don't work out for a simple design (i.e. with not much IP revealed by open sourcing the spec) that can be programmed with OS tools. I mean, there's these ICE chips, which is a huge step, but realistically I'd want something just a tiny bit bigger and with a hardcore (ARM or MIPS) in it.

Or maybe the market economics work out, but are small relatively compared to the big players, so it moves glacially.
