True as well...

It is extremely low-level approach to the problem and it's possibly duplicate existing in system messaging like UNIX domain socket or POSIQ MQ.
Additional overhead for providing reliable communication would be difficult to achieve and would have significant impact on performance.
Good, it should be pretty trivial to implement within the framework.
In my opinion using UNIX domain socket would be much more beneficial to ROS and much simpler to implement.
Do you have experience on how the performance compares with TCP over loopback?
I'm beginning to wonder if the biggest quality of the sharedmem plugin will only be to make sure nobody (else) loses time to implement it...
Thanks for the feedback
