   Kaval Wireless Technologies Inc. uses Python in a variety of ways 
   in the development and production of its wireless coverage extension
   systems, as well as using it in some of the products themselves.  The 
   PyPy project holds great promise for improving the performance and
   cross-platform nature of the Python environment, and I look forward 
   to seeing those improvements occur.

   I'm interested in PyPy because it's about Python, the
   pragmatic language that I use for my business and make my living with, and
   because it promises pragmatic benefits (performance is my personal
   #1, but there is a lot of other potential).

   I am one of the main developers of the open source Twisted networking
   framework, which is used by organizations ranging from NASA and
   California state agencies to individuals and companies in the US, Italy,
   Sweden, France and the Netherlands. I would like to see PyPy succeed as
   the result would be a platform that is far superior to competing
   software platforms, while still being open and not tied to the fortunes
   of one or two American corporations.

    I'm an independent software developer and consultant. My current
    focus is the development of design tools, code generators, and
    monitoring tools for embedded, distributed, real-time systems
    (often applied in safety-critical domains). I have been using
    Python with great success for these application domains.

    A successful PyPy would increase the benefits of using Python:

    - it would allow me to even more functionality into
      Python and further reduce the amount of C code needed for the
      on-line part of such systems (which is running on PC-class HW).

    - it might allow to replace (some but not nearly all) C code in
      the embedded parts of such systems.

    - it might substantially improve the performance of the design
      tools and code generators.

   As a vendor of development tools for Python programmers, we support PyPy
   as an important step towards advancing the technology behind Python
   programming language
