A webinar from GeoConnections:
The webinar will be structured in two parts. The first part will focus on organizational use of common open source software licensing models, while the second part will explain how organizations can license the software that they have developed for use by others in an open source environment. The session will close with a question and answer period where you will be welcome to pose questions to the presenters.
It's Oct 25, free, open to all. It's not clear if the focus is on geospatial software in particular or open source software in general.
Only one issue with the text above, Leaflet is not an organization, but an open source project from Cloudmade. Per the webpage:
The Quantum GIS (QGIS) project is happy to announce that the Asia Air Survey Co., Ltd (AAS), a Japanese international consulting company, has become a Gold Sponsor. AAS has committed to providing 9,000 EUR (~$11,000 US) each of three years, beginning in November 2012.
