Rob,
I'd estimate the priority of this feature as very low. There are some
reasons why this is less important for Virtuoso than for Oracle:
1. Virtuoso integrates web server and the core of RDBMS in a single
process, so page generation can be made by a Virtuoso/PL stored
procedure from beginning
Does Virtuoso use an MVCC architecture?
I wondering if it has support (or planned support) for something like Oracle
Flash back queries.

Thanks, Rob.
