I do a lot of record level buffering for any tables open for read/write,
rarely table buffering. Most of my tables with multi-user utilization are
opened read-only. Thus, I may be able to skirt around some of the issues
that have plagued Ted. But, I am certainly open to any input from others
that have gone down this road already.

I guess that all-in-all there is no true perfection with any technical
approach to solving challenges put before us. It has always been a matter
of tweaking to get things as perfectly balanced as possible for the project
at hand. New(er) tools = newer opportunities to find the need to do more
such tweaking I guess <g>...
