I for one support rewriting NetworkManager. It has existed for, what, half a decade now, and still fails to support many basic use cases that "just worked" out of the box even on Nokia N800. Add to that its heavy memory footprint and you really start to wonder if you want it on a small device...

On the other hand, NetworkManager's habbit of doing just about nothing by itself, and needing distributions to add lots of glue to even give you a config file, it sounds a bit like it'd be at home with MeeGo core's policy of being a base for distributions/integrators ;-)
