The only part I'm not too keen on in your version is that the .tgz gets left on the empeg after the install process is done. Given the apps partition is only 30MB, I'd rather it be removed (in anticipation of an explosion of 3rd party app development )...

Oh, I don't know abount the M0appinstall, either. I think it might be a little excessive -- I mean, how often do new apps appear (in anticipation of the aforementioned explosion never occuring)? However, I can't think of any other way to get apps installable by JEmplode...
