Is double parton scattering merely something of curiosity, or is it useful in the production of interesting particles (Higgs, top, B meson etc.)?

Useful? You mean marketable? :)

It's important in understanding the backgrounds to various signals. For example, a background to, say a W + 2 jet signal would be a W produced by one scatter and the two jets by another.
