Have you looked at ReSharper? It does usage highlighting (http://www.jetbrains.com/resharper/features/navigation_search.html#Highlight_Usages http://www.jetbrains.com/resharper/features/navigation_searc...) The extra functionality it adds to VS 2008 & 2010 is really useful. I started using it about a month ago and kicking myself I didn't invest in it ealier.
