As the originator of FreeB I am usually up on whats happening in the open source medical billing world. Imagine my surprise when I found out that someone has put out a really excellent X12 parsing and validating tool! John Holland has written and excellent python library called pyx12. Of course I wish he had released it under the GPL but it is still an excellent F/OSS application!

Does anybody know of any other interesting X12/HL7 F/OSS projects?
