[ros-users] Use cases for ROS on ARM based computers

I understand your points and in a crowded environment I would strongly
support it. However, many SIGs are/seem to be very quiet. That's why I am
worried about new SIGs dying even after a powerful start as it happened to
many SIGs before (just have a look at the Fuerte&Groovy SIGs).

I think, the chances for a SIG to stay active are higher the more people
are interacting in it. And even though the focus of ROS on ARM might be
different than what has been discussed on the embedded list so far, both
groups could still benefit from synergy effects, such as overlapping
topics, help from experts etc. And last but not least, it would be easier
for ARM/embedded newcomers to find a starting point (e.g. I'm using an ARM
board, but which group is the right one for me (ARM Cortex A8/9 vs M3/4)?).


PS: In case you still want to separate, please clearly point out, who is
your target audience for the list. Thanks.
