The more the merrier! The thing is... as long as your source on Github does not contain AllM's intellectual property, then it should be fine.
You would likely have to avoid posting the .b files, the .as files, but the rest would be code you have written yourself.
Have not attempted porting the server executable to another language, because that is beyond my expertise, and a whole other level of effort in itself. In one of the lunia posts, there should be an "allm-xrated.zip" somewhere. This is the 2.6 source code, which you can use alongside the previously release CN_1.8 source code that is floating everywhere.
The more the merrier, I am sure people would be ecstatic for a Python+Postgre version, especially if it simplifies getting a server running!
