In the specs suite of
cross-stub, i've built a custom echo server using
this approach to support testing of stubbing in another process. Nothing wrong with it, except that it is not so fun & clean. Anyway, over the weekend, i've extracted out the echo server code, and put it inside a new & fun project
otaku.
Here's my tidied up specs (which serve as a good example usage of
otaku):
