Simple, yet production-ready flash policy server.

Distinguished from other similar projects by using async IO (no threads), which is the only sane solution for such a task. I use it in production environment with ~20k socket connections to server. And it copes quite well thanks to async IO of Twisted.

Features:

1. Asyncronous IO (no threads) for production scalability
2. Optional Monit resource file for continuous sanity checking
3. init.d script
4. Configurable flashpolicy.xml
5. Only 20 lines of Python code!

Installation:

1. Install Twisted (Ubuntu: sudo apt-get install python-twisted)
2. Install flashpolicytwistd itself. Ubuntu users can download deb package and sudo dpkg -i flashpolicytwistd.deb.
3. Optionally, modify /etc/flashpolicy.xml
4. sudo /etc/init.d/flashpolicytwistd start
5. Optionally, install Monit. The package above provides /etc/monit/conf.d/flashpolicytwistd. Update Monit configuration to make use of it.

Comments are welcome.
