OpenWengo Code Camp

詳しくはリンク先を見ていただくとして、PSPへのポーティングプロジェクトも存在しているようですね。

Skype（スカイプ）もPSPやDSへのポーティングしたりしないのかなー

Available Projects

Several FOSS development projects are involved into OpenWengo Code Camp 2006. It is very likely that you'll find a project to scratch your itch on in the proposed projects page. Proposed projects range from a graphical XUL editor to porting a VoIP engine to the Sony PSP®. There's even an open project for which you can submit your own project idea!
