Well, I find it interesting as well :)

The term has too many meanings to find anything useful using google. And cog-related, there is only the article "An Arranged Marriage". In that, an understanding seems required. Do you have any more sources where I can read about trampolines? Or can point to the paragraph where they are explained?
Normally, I would assume Eliot refers to Lisp style trampolines.
See http://stackoverflow.com/a/489860/916546 for some explanation.
