Transferring shares between tenants is not something we've discussed 
before. The cinder project allows transferring of volumes but its easier 
for them to implement that feature because they don't have the concepts 
of share networks and share servers to tie the share to a tenant.

We implemented "public shares" which allows a similar use case where 1 
tenant can allow others to read/write to a share and should address many 
of the same use cases that share transferring would address.
