That is the limitation I ran into with the vertex_array objects.  The 
objects are fast and have very few limits but Pd really has no way to 
deal with the data effectively.

Using messages is not precise enough even though it does fit the more 
programmatic aspects of control in Pd.  Maybe a special GEM data 
display window with dedicated mouse and keyboard controls could help 
with the viewing and selecting of data in the arrays?
