Not without customizing the specialist's code.  In PEAK, however, there's a 
new kind of specialist called a QueryDM that can do this (i.e. load state 
for a large number of objects at once).  Unfortunately, PEAK's 
web-publishing framework isn't ready yet, and as far as I know nobody has 
created any integration for PEAK into Zope 2.
