I reported a software bug in a commercial package (Allegorithmic Substance Designe) a few months ago. The support guy told me that, to help me, he wanted me to install a VNC server, send him my id and password, and let him have access to my machine so he could debug the problem.<p>When I balked he acted all offended and told me they work with some of the biggest companies in the industry, they see lots of stuff on customer&#x27;s machines, and are totally trustworthy.
