I tried this and it works great. I don't remember if it was noted in the show but you need to supply the port number. On my kindle 3g with keyboard, it's hard to read the pages.  Had to play around with display settings and reload when the pages got garbled.  But it did work.  I think I'll probably plug in the 3gs if possible though because it takes me a while to get to the page.

Worked much better on the Kindle dx.
