I would rather not think of Excel, thank you.
VOplot would be more powerful if/when it  understands an SED and 
instantly plots it
with both vertical and horizontal error bars and can call up metadata  
on any datapoint when you click on it (including filter name and 
response function, telescope, observer, date, and aperture size) and can 
provide either frequency or wavelength axes.  Maybe it will handle 
addition of the users data and write out a new SED.  Likewise for each 
of the half dozen or so DM models that are envisioned.

For dumb tools that only know VOTable there can always be a generic XSLT 
to transform a DM object into VOTable.  There would usually be some loss 
of information so it is not reversable but this is good enough for the 
purpose.
