Anyone using Scheme/LISP for embedded projects?

This question is maybe somehow inspired with Anyone using Python for embedded projects?; so anyone using some Scheme version or Common Lisp (like ECL) for free/oss/commercial projects?

Personally, I used (and still using) TinyScheme for personal projects where some embedded language is needed, mostly due extremely easy embedding (sorry Python lovers, been there and that is quite painful, especially after I learned 开发者_开发技巧from TinyScheme how things can be simple).

The most prominent project I remember hearing about is (Gambit) Scheme on the iPhone. It was shut down by the user agreement for a while but I suppose with the new one, this kind of development is allowed again.

I don't see it on the page any more, but I remember a related blog post about interactive development on the iPhone using Scheme. Very exciting.
