Not yet sure whether anything here is useful, but I found the sticky app thread on slatedroid for the Pandigital Novel (now that they are hacking it into an Android tablet).

I'm assuming if they can get those apps working on a 7inch tablet, we should be able to do the same? (Not sure which version of Android they're running, though.) Just thought it might be worth a look.
