how to combine multiple related applications in one project/site

We’re a small organization with limited sysadmin support and a low thruput requirement.

 

I’ve got some common features  that are evolving that are used in all projects, even though the projects themselves are unrelated and on different servers.

 

I have a very specific logging function to a mysql DB (same server, different database) to comply with gov’t regs.

 

I’ve got a very specific security feature that queries some legacy code via HTTP and another MYSQL DB (again a separate database from the main application).

 

I’m using django 1.5.1 and Python 2.6 on CentOs

 

I would like to use the same code in various projects.  Should I move these features into separate django applications and if so, how should I structure my directories and imports to keep it clean.

 

I suppose this might be a candidate for middleware, but I’m the only guy working on this and cannot devote much time to “infrastructure tangents” no matter how good they might be.

 

I would appreciate a little advice on the good, bad and ugly solutions to the above, based on the communities more extensive experience.

 

Thanks,

 

Fred.
