I don't think common use will likely crash it: e.g. images and point 
cloud are not always changing size. And the nodes should not crash if 
the object size stays constant.

I have a theoretical use case for the sharedmem plugin which is 
"exchanging very large objects between processes that cannot be 
converted to nodelets, and with reduced delay or reduced network 
clogging".  I am not sure this corresponds to a problem people really 
have, so I'm waiting for feedback on that. I would say this part of the 
code is in beta, sufficiently functional to raise interest and to be 
tried in controlled situations, but I agree it still need to be worked on.

Actually, all this generic message transport is a nice theoretical 
concept, but I'm not sure how much of it is solving a problem people 
really have. It was fun to develop though.

Let's wait and see.
