Greetings,
Are you aware of any file size limitations? I have 200 files I'm attempting to combine that total 2GB.

This does not work with python2.6 which is still the most installed version in production environment. Knowing no python, I'm doomed :-) I tried this, but it's growing over my head: http://stackoverflow.com/questions/13667979/python-2-6-1-expected-path-separator

This is great for smaller files, but i have 40 reports that push through to a 1Gb .nessus file. it takes a good 5Gb of RAM to run this. if anyone knows of a script that uses iterparse (or similar), it would be great to see.

This works perfect. I merged 56 reports with more than 25,000 hosts.
