It's on an internal todo list, but has been delayed for two reasons.  First, there was a bug in proto 2 that didn't get fixed until Python 2.3.4, so 2.3.4 is an absolute minimum requirement.  That delayed even thinking about this seriously for a long time.  The other reason still exists:  since proto 2 pickles can't be read by older Pythons, then, for example, a Data.fs created after switching to proto 2 can't be used under any older Zope/ZODB installation.  That hard incompatibility makes it seem prudent to wait on this a bit longer.

For efficiency we should  use pickle protocol 2 instead of protocol 1.
