Not likely, I think it has been more or less established that iBooks uses Apple DRM - they have definitely not licensed Adobe's DRM, for example. But there will be iPad apps to access other online bookstores, including Kindle, txtr, etc., unless Apple bans them (a possibility, but IMO unlikely).
So while it would be nice not to have to have 6 different apps to read 6 different collections of books, I think that's likely to be how it will work on iPad. Portability between devices will not be achieved except by each bookstore offering reader apps for each, as many are starting to do.
