Mobile Sorcery MoSync. This is a similar concept to Red Five Labs in that you write in one language (C/C++) against the MoSync API and this is compiled to an intermediate language that’s interpreted by a runtime on the device (Symbian, Java or Windows Mobile). I asked about signing/Symbian capabilities and was told that apps are self signed and MoSync can’t be used for more complex apps that need capability restricted APIs. Again, it’s planned to sell this on a per-runtime basis.
