• iTalc, http://italc.sourceforge.net Free downloadable "tool" designed to allow teachers to "view and control" other computers in the network.  I haven't used it, but I think it's similar to products such as Synchroneyes that, while they do have useful applications, can also have a "big brother is watching" affect. 

• Ithenticate, http://www.itehnticate.com/ "iThenticate is a proven tool that gives publishers, corporations, law firms, and others the power to check the originality of documents and manuscripts instantly. It also allows these entities to find out if any of their current intellectual property is being misappropriated somewhere on the internet." I haven't check this out, of course, and I probably won't.  Plagiarism detection services like these just aren't really the best way to go, imho. But it's here if anyone is interested in trying it out.  [Posted 15 March 2008]

• Nicenet's Free Internet Classroom Assistant  I haven't checked this one out yet either, but it looks intriguing.

Okay, I’ve tried it, and I give it a negative 5. For one thing, it doesn’t seem to be able to tell the difference between plagiarism and quotation. For another (and even more important) consideration, I don’t like that student submissions become part of its database—which they make money off of. And, oh, gee, there are SO many problems with this….. [Posted 4 Nov. 2006].
