First of all I want to say that I like the idea and am already 
desperately missing Expression Templates for boost::multi_array, to use 
as a nice boost-compatible replacement for Blitz++. I thus support 
anything which can give me these features in a clean way.

Having said that I doubt that you will solve ET programming once and 
for all with your library. As I had shown in a presentation at 
ISCOPE'99 some time ago, extensions to standard ET mechanisms are 
needed when including operators, such as (a maybe too simple example), 
when wanting to write A = Laplace*B for applying the Laplace operator 
to an array, since operator* is evaluated from left to right while 
operator expressions are evaluated from right to left.
