Parenscript

Parenscript is a translator from a small Lispy language to JavaScript. Parenscript code can run almost identically on both the browser (as JavaScript) and server (as Common Lisp). Because Parenscript code is treated the same way as Common Lisp code ... [More] , the full power of Lisp macros is available to the developer, with the added flexibility that macros can either be shared between CL and PS, or have different expansions in either environment to enable the same application code to accomodate differences between browser and server. Due to this ability and the tremendous code-generating power of Lisp, Parenscript provides a web development environment that is unmatched in its ability to reduce code duplication and provide advanced metaprogramming facilities to web developers.

Hmm so I could run Lisp and Ruby both in a Java VM. Perhaps my dream of Rails-plus-Parenscript is getting nearer?
