You might want to look into memory grids like:

• Oracle Coherence: http://www.oracle.com/technetwork/middleware/coherence/overview/index.html
• GridGain: http://www.gridgain.com/
• Terracotta: http://terracotta.org/

We use Coherence to run 3 JVMs on 1 machine, each process is using 1 Gb of the RAM.
