The only place I've noticed rikaichan failing to work is when the kanji is inside an image, such as a gif. I'm not exactly sure how it works, but as a computer programmer I can guess that it has to do with the character code of the character under the cursor, and those to the right of that one. As such, it is a client thing, and not a server thing. So, it really should not matter how you got to the page, just that it has text that you can cursor over.
I'm not really going all over, just yet, in trying to read stuff. Basically, just here (mostly) and Tae Kim's grammar page. The reading tutor home page (do you know it? With a cute little mouse with round glasses?)
