LMS in Python/Django/Ruby/Rails/PHP
This is a real problem as open-source LMS are all in PHP, with the exception of Sakai which is in Java.
As I've written a LMS which tries to be compatible with SCORM I can say that it's not a small work to create a SCORM implementation. 
The only project in Python I know is Cloud Course, created by Google on GAE (http://code.google.com/p/cloudcourse/)
You can also use Rustici's SCORM Cloud with Python (https://github.com/RusticiSoftware/SCORMCloud_PythonLibrary)
I am looking for an alternative to Moodle.
I searched and found pinax-lms-demo, which was Django-based;
and Astra which was Rails-based, but both were empty repo...  
I need a LMS which has the following functions:  

create class  
Assign faculty  
Upload materials  
Take quiz  
forum  
scorm  
chat  

I spent more than a month using Moodle and being a developer I felt I should not use it...
