VisAD disk requirements

How much disk space (approx.) does the VisAD package(s) occupy ?   

Our target system's (a Sun  workstation) SysAdmin says he needs to know
before we can proceed with the install.

Thanks,

P.S. : If you happen to know Vis5D's disk usage , that could also be helpful
downstream.
