I recently had an urgent need to find a hard case for travel with my BeBook (the displays may be quite fragile and it is important to protect them), and my partner came up with the following suggestion.
For a BeBook with the Stylz cover, an old VHS tape box - the hinged plastic boxes used by video rentals and libraries fits perfectly. The internal corners used to locate the tape cassette support the BeBook away from the screen, ensuring plenty of clearance between the case and both the front and back of the reader.
Grab one while you can, these cases are getting hard to find these days :-)
