Yes, in the case of the ASP model, but also in the case of 
inhouse-deployment. Or if the product is embedded in a proprietary 
larger work (or in general modified and distributed without source 
code), which the Copyback license would allow.

The Copyback license would grant certain freedoms that the GPL does 
not, but limit some others that the GPL does grant. At the same time it 
would keep code "more free" than the BSD (in the GPL way of thinking).
