Ibis Reader is an upcoming e-book reader built for Android, iPhone, and webOS as a web app. It uses HTML5 for offline storage and will have cross-device syncing and bookmarking so you can start reading on your iPod touch and pick it up where you left off on your Palm Pre.

Ibis Reader uses BookServer for its content and all of the books are completely DRM free. They’ve even gone so far as to allow you to export your books and put them on any device that supports ePub.

The app won’t be launching for several months but I’m excited to see where it goes.
