e-reader software for Blackberry

[Anonymous]

Does anyone know of Blackberry software (freeware or not-free) that will let me read books created for Sony & Kindle readers? It seems like there should be software that mimics the reader devices, but I have not found any. I've got MobiPocket, and that works for some books, but does not seem to allow for DRM-protected books from the library.

I know this is a long-shot, but there are some pretty tech-savvy people here. Any help appreciated.
