Ruby HAML with Django?
I strongly recommend that you do not fork any processes out of your django views, because the overhead is significant. 
You should have a persistent ruby process to serve your templates for you, and invoke it from your django code. I leave the IPC technology to you, but the obvious choices would either be some kind of message queuing technology, or speaking HTTP over a socket to the ruby process.
Ok, so I really love HAML.  Particularly, I love the integration with RedCloth and BlueCloth, so I can use Markdown and Textile intermixed with my HAML.
I also love Python and Django.
So, I would like to use HAML with Django.  Now, I already understand that there are some attempts at cloning HAML-like syntax in Python (SHPAML and others).  I've tried these, and while they aren't bad, I've found that I really just want the real HAML.  Partially for its syntax, but also for things like RedCloth and BlueCloth.
So, my question is, how to make HAML and Django work together?
One solution, I think, would be to create HAML templates, and then compile them into HTML using the command line tool every time they're updated.
Quesiton 1: Will I run into any problems here?
I also wonder if there's a way to get Python and Ruby to play together a little more.  One idea I had was actually forking out Ruby processes.  This is probably a bad idea, but anyone have any thoughts about this?
Question 2: What about using Python to call the real Ruby HAML?
Finally, if anyone knows of a Python implementation of HAML that is complete, and that supports either Textile or Markdown, as well as plaintext passthru, then let me know.  
Question 3: Is there a full translation of HAML to Python including Markdown or Textile support?
Thanks!
