@Leopold: In case you're not aware, you need only drop the tar file into the Update (.update) folder and reboot for OpenELEC to upgrade, although of course this only works with recent Gotham builds so you'll still need to extract SYSTEM/KERNEL/MD5 when upgrading from Frodo. If you were able to determine if tar upgrading is supported, your addon would have to do less work (just download to .update, basically).
