Are you looking for free/open source alternative queue manager for batch jobs and you like python.. Look at fireworks

  
this toolkit is a very competent queue manager and server running in python and can be used to batch anything that you could start from commandline or write your own python code.

It takes some getting used to and you definetly need to know some python to make it work with 3ds max.. But it works great and I use it for baking, optimizing models, or just imagemagic processing of millions of files.

It uses MongoDb at its hart which works very well for me.

I recommend it highly..

An example of the many functions that I really like.. Complex depency graphs.. You can create workflows for example you can have one job that spawns more smaller jobs like an animation file that generates frames.. Then when and only when all frames are done another step will assemble them all into a .mov file..

(This is from another example in the tutorials)
