Sure, IMO. One possibility is to use the array template argument of  
numerics::vector (or numerics::matrix ;-) to adapt your own storage 
container. The only known restriction of the current CVS version is, 
that you don't have access via a data() member. This will change in 
the next release (due to an earlier remark of Peter Schmitteckert).
 
Another way is to write your own adaptor class, see the packed matrix 
adaptors for example.

You've lost me. Could you explain this requirement, please?
