An E field has an inertial mass? 

Mass measures the amount of an object's inertia.  
OK, let's hypothesize a E-M pulse through a vacuum, 
of very low dispersion.  It occupies a finite volume, 
of finite duration; a 'cloud of radiation', so to speak, 
flying free.

Now, what does inertia mean, in this case, of a 
non-material object?  As gedanken experiment, how 
would one measure its mass?
