Python implementations matrix - Misspelled Nemesis Club

For the last week or so I’ve been putting together a spreadsheet, to compare the various Python implementations on support of PEPs and library modules. It is ready for a first release, but far from complete:

CPython 1.5 - 2.5 coverage is good.
IronPython 1.0 - 1.1 has library coverage
Jython only has release dates
PyPy has not been started

I’ve uploaded as an OpenDocument Spreadsheet: Python implementations matrix. Alternatively, for those stuck with Excel, it is also available as an MS Excel workbook: Python implementations matrix (xls) Comments, suggestions and emails welcome.
