They aren't mutually exclusive, but a content-based approach, although more flexible, seems like it would inevitably be much heavier weight.

Now when the topic of Copy-on-Write memory sharing is up. It might be in
place to tell that we (a group of tree master students), will be doing
work on content based Copy-on-Write memory sharing. Similar to what is
implemented in VMWare's ESX server. See
http://www.waldspurger.org/carl/papers/esx-mem-osdi02.pdf

We have contacted Michael Vrable about his approach, and it is likely
that our code will be an extension of his.
