Perhaps you(Waugh) thought that bidirectional replication means you can access the lun on both the source and target side simultaneously?
If so, that setup is as mythical as the user awhile back asking about zero RTO. It is not possible, no matter who the manufacturer is. You might be able to fake it by merging the fabrics over a private fiber and accessing the primary site array from the dr site, but that is a horrible idea from a performance and reliability perspective.
Take a look at vplex before you say it's impossible. Of course this design gets even easier when we get VMware vvols because the unit of access and replication becomes the vmdk rather than the lun.
