Gman: No, I was very happy when Sun joined the fundation. The two cases can not be more different. Sun said that they would contribute to GNOME development using GNOME technologies and using the GNOME licenses for their contributions.
Real on the other hand is wants to present software not using any GNOME technologies, not integrating with GNOME in any way and which uses a license that is not compatible with ours. In fact the difference between having Microsoft come and present their streaming media server and having Real doing their presentation is marginal in relation to GNOME.
But I guess if Real is joining the GNOME Foundation (or sponsoring GUADEC directly) I guess letting them talk is fair enough, especially considering how dry the sponsor money has been this year.
