I have just put up a poll on language bindings or development environments folks would like to see supported. I'd like to give folks an idea of my thinking behind each of these reasons and a chance to discuss the options and perhaps add more. Again, anyone who would like to take on the actual work for any of these, I would be more than happy to help out a bit.
PHP: This might be a good way to get e-commerce stuff and shopping carts added.
Python: Python is a popular platform and there might be a lot of input we could get there.
Lisp: Lisp has a great reputation among certain groups of programmers. It may be a good way to help attract top-tier talent to some things we are doing.
Ruby: Ruby has huge mindshare. This would not be Rails bindings of course but just a Ruby gem designed to provide query mapping services.
Java: Larger businesses may be happier if we have Java bindings.
_javascript_/Node.js
LUA: Make it even easier to customize workflow-wise.
