a couple of things here.  First, please dont be discouraged.  You've picked a tough topic to contribute on, |verifiability is going to be tough to meet.  The USENET posts you  cite above establish that the software exists, but doesn't address notability concerns.  USENET posts are going to be treated like blog posts for purposes of determining their |reliability.  Unfortunately those are not reliable sources
