A while ago Red Daly posted about some great initial work he had done in porting ECL to the iPhone. I contacted him, and worked to clean up some of the external dependencies, and got ECL to run on the simulator and device (with SLIME). I put together an updated Git repo with all my changes, and finally got around to posting about it.

Hopefully, this will be of use to others.
