ECMA-327 (ECMAScript Compact version) implementation on .Net Compact Framework

Dear WG members,

Do you know of any such implementation, possibly free/open ?
I know of ecmascript-net (http://code.google.com/p/ecmascript-net/), however it is on low maintenance and not available for .NET CF. I can't seem to find an implementation that matches my needs.

Thanks 
Sebastien
