I wonder how close the "piper" system is to the code.google.com project.

I worked on code.google.com, i can tell you the are 100% unrelated.

piper grew out of a need to scale the source control system the initial internal repositories were using

code.google.com was a completely separate thing supporting completely different version control models, and a very different scale (very large number of small repositories, vs very small number of very large repositories)

IIRC, Piper is a reimplementation of the perforce backend, in order to handle the code size and the sheer number of "changelists" submitted per second. Nothing to do with code.google.com.

They are unrelated. :)
