Ah, simple.

Has anyone got any giant magnetic accelerators?

Laserlight, you of course right. The amound of kinetic energy required
to 
shift venus is quite a lot. but then again, even in the Tuffleyverse
large 
starships are transported across the universe at speeds greater then C,
and 
that requires a lot of energy too.
