I understand that the CMB dipole for the solar system is estimated to be 368 km/sec ... can we draw any implications from this?

Jeff,
It's meaningless because the implication is that the universe was created in existing space. Space-time was created at the BB. From a topological perspective any point in the universe can be considered the "centre".
