I'm subscribed to a thread on the networker online discussion group where it 
talks about when networker will support the vstorage api's, which a lot of us 
who currently use vcb are awaiting.

In the response from emc is a sign-up for beta testing and also a revised 
timeline for 7.6 SP2.

The entire link is located here just in case anyone else was wondering about 
vstorage api support:
