3rd party VMS-Ultrix Connection like product

[Robert D. Haskins]

We're looking for a product that works similarly to the DEC product
VMS-Ultrix Connection.  Nameley, we would like to have the ability
to do NFS remote mounts onto a VMS box or be able to access directly
the tape drives located on the VMS box.  Does anyone know of a
beast (other than the obvious VMS-Ultrix Connection product) that
would accomplish this?
