Books/Albums in Aperture 1.5

I really like how you can work with images right within Aperture to lay out books, but it it willl be even better when companies like Asukabook and GraphiStudio can produce a plug-in that allows for book creation in Aperture. As it stands now, you can only produce a few specific size books, say 9x11, and the end quality is not that all that classy for high-end clients. The books themselves are more useful for proof books, portfolios, and possibly thank-you type gifts.
