Since no one else has answered allow me to try.
Currently, no. Two or more instances of MAME cannot communicate with each other.
Long term, I believe the hope is that MAME will allow multiple instances running on the same machine to communicate. This would, of course, require the the machine has the power to run multiple instances simultaneously.
Over on the programming board there is a rather exciting and long thread about SailorSat's work on emulating the Model1 communication board. Of particular interest is that this works over the network allowing separate machine to communicate.
While it solves a different problem, you might also look at MameHub which is based on Client Server MAME. It allows users to play single-machine games with multiple players over the internet by synchronizing inputs.
