Thank you. I was kind of hoping someone would have suggestions for further reading. :)

Alastair Reynolds wrote a short story with this as an element. I think it's in Zima Blue.

Greg Egan goes into such things at length in Permutation City.

Thanks, I'm looking forward to some inter-dimensional reading!

Anathem is a great book that explores lots of interesting, fairly unique ideas, and does some moderately original world building. But I always tell people Stephenson (the author, personal favorite) isn't for everyone, and Anathem isn't even for all Stephenson fans, it can be a hard read for many.
