I wouldn't use it because
(a) nobody's going to uninstall or reconfigure software just to view your site, so the only purpose it really serves is to vent your frustration;
(b) many people don't have the knowledge or authorization to do that anyway;
(c) such traffic can still have beneficial results such as inbound links, word-of-mouth, or return visits from PCs that show ads;
(d) my site uses diverse revenue sources, including static ads;
(e) you'll be banning Googlebot and other desirable spiders unless you go to a further level of cloaking.
