But I suppose pypip would be a reasonable name. pyinstall doesn't read right now that it's a two-level command. python-pip seems unnecessarily long-winded.
Note also that with virtualenv 1.4.1 (newer than the current Debian package, I think), pip is automatically installed in all new environments. Meaning you do:
$ my-env/bin/pip install ...
It would be inconsistent with many online documents to rename this binary. At the same time, there's no particular conflict since that script is localized to a Python-specific environment. Which I guess makes me think: I'm not particularly concerned with the system-level packaging of pip, as I think system-level Python libraries should be installed through the Debian packaging system, and pip (which doesn't use Debian packages) should be used in concert with virtualenv to install local versions of libraries.
