There's no conflict here --- we're not talking physics problems,  
we're talking engineering problems, specifically miniaturization  
problems.  MEG could be dramatically improved through some relatively  
minor advances, and some new materials seem fairly promising.  Having  
trouble w/ del.icio.us at the moment so I can't find the links I'm  
looking for, but here's a (now rather dated) flyer from an earlier  
conference that mentions MEG applications in passing:
