Jumbo frames can certainly be helpful within the IDC, for example  
between front-end systems and back-end database and/or storage  
systems; the IDC is also a more controlled and predictable  
environment (or at least it should be, heh) than the aggregate of  
multiple transit/access networks, and therefore in most cases one  
ought to be able to ensure that jumbo frames are supported end-to-end  
between the relevant IDC-hosted systems (or even between multiple  
IDCs within the same SP network).  This isn't the same as a true end- 
to-end capability between any discrete set of nodes on the Internet,  
but they can still indirectly increased performance for a  
topologically diverse user population by virtue of more optimal  
throughput 'behind the curtains', as it were.
