It was not a virus in the traditional sense - it was fairly benign but malicious running code. Should the Technic team have chosen to, there were people here willing to tweak that code out of Forestry, and they probably could have done it themselves anyway, so I don't think they were made to, per se. I just think they decided it wasn't worth the hassle.
