I tried TraceMonkey when it came out and it was not too hard to swap  
out.

It's all external.

See your default.ini file:

[query_servers]
javascript = /path/to/couchjs /path/to/couchdb/server/main.js

You need a binary that can run main.js and place it into the above  
directive.

That's it.

Let us know what you find out! :)

Cheers
Jan
