Update: If you got this plugin yesterday or this morning, make sure to download a new version. There was a bug in the cleanup script that could delete files it didn't create, (which would obviously cause some headaches depending on where you export your doc...).
Georg Kaindl has written a web export plugin for VoodooPad, which encodes an entire document (including images) into a bookmarklet, which you can then view on your iPhone (freaken' crazy awesome!). This works today, no SDK required. It doesn't work for big documnts, but if you just have mostly text... this is for you.
Check it out on his VoodooPhone page.
