I am just looking at the PSF license now as it goes. It does appear that we should be able to continue using matplotlib. - the restrictions on open-source that have been imposed specifically state it is fine to use the python language, and if matplotlib has the same license I personally can't see any issue. However, the decision is not mine.
The company I am with is unsure, and while they will pursue the possible use of matplotlib with the PSF license, they would prefer I continued to look into any commercially licensed libraries that could be used. ...and as it goes, the first thing I fired back at them when I was told 'no open source can be used' was basically 'What on earth are we going to use to code it in...' and that the 'no open source' restriciton as given was overly broad when you think about it. -- http://mail.python.org/mailman/listinfo/python-list
