Richard Thomas, creator of the jQPie helper application (PHP for jQuery) is suggesting a broader scope for the project in his new blog post:

Now I have slightly larger goals, the Pie represents the slices of code I hope to pack within. Currently there is a php5 slice, and another person has shown some interest in working on a php4 version.

Now I am looking for you! Yea you there the one looking at jQPie thinking it would be cool to use but your knee deep in Python, or Perl, or any other language.

His ultimate goal is to have a single javascript library that can span as many languages as it can right out of the box. To help the effort along, he's offering 2 cash prizes to developers - one for the Python/Ruby-ers out there and the other for Perl-heads. The best, most complete (working) library wins. Keep an eye on his blog for more details on the contest and when it starts.
