The PyKDE4 bindings will be made using SIP.
As of 1-Sep-07 PyKDE code is essentially complete, except for Phonon module support. The package should be in KDE SVN soon. Current work is on examples, docs, and related tools (pykdeuic, etc.) Anyone wishing to work on either example code or test code should contact Jim Bublitz - jbublitz@nwinternet.com.
