[elephant-devel] Multi-repository operation

[Robert L. Read]

IMHO, multi-repository operation is mainly valuable during migration
from one 
implementation to another.  I don't believe support cross-repository
transactions
if valuable, compared to other improvements that could be made.

But please, don't let my opinion keep others from commenting.....
