My 2 cents.

Maybe just run pypy on Travis-CI instead of the buildslaves

There is this PR https://github.com/twisted/twisted/pull/226

and ticket

https://twistedbumatrix.com/trac/ticket/8505


---------

In that ticket there is one way of solving this.

Instead of using using Ubuntu or Debian packages, just use OS
independent method to install latest PYPY.

Glyph, do we need Debian/Ubuntu packages for PYPY installed on the slaves?

-----------

For designing the buildbot builders maybe we can get something similar
to Travis-CI.
Before running the tests, buildbot will call something like `python
admin/buildbot-init` and depending on the environment variables, this
script can install various things.

In this way we have more configuration logic in the repo and
developers can advance the work without waiting for someone to upgrade
the OS
