Zemlin said Moblin, Android and LiMo have several technologies in common -- not the least of which is the Linux kernel. Proponents of each also boast that they individually offer an open development platform for mobile devices that developers can modify as they wish, although they use different open-source licenses.
Android, for example, uses the Apache license, which allows developers to modify the code of the platform when they implement it on devices but does not require them to give that code back to the open-source community. This could threaten the compatibility of Android across different devices as developers modify the platform but don't let others in on the changes.
LiMo, on the other hand, requires developers to share the platform changes they make with the greater community. Zemlin said the bulk of Moblin is licensed under the GNU General Public License, which also obligates developers to share their code with the community.
However, he acknowledged that there are so many different open-source technologies and projects used as part of Moblin that "I couldn't even tell you what every single license is."
