To start with, adding a = compression library that is directly accessible to the network on = financial software is a really, really scary idea. I have the same opinion. On the other hand, I can imagine using compression on local blocks = storage (be it compressed filesystem, or compression in the user = space/in the application - compare with = https://github.com/bitcoin/bitcoin/issues/2278).
