Legality aside, I'm not sure it's possible. I thought the ebooks were tied to our hardware, one way or another. If you bought them from Sony, then I think they're limited to hardware registered to your account. If you bought them from Books On Board (ADE), the Adobe initialization ties them to your computer and Reader (I think - I don't like Adobe's DRM, so I don't use them).
Now, if you're buying DRM-free ebooks...well, back to your regular programming, already in progress.
