Pat,
Just be warned, not too many people are up on VDS these days, try to get directly to Developer level support.
I did make a little progress by changing the filter in the Database node. In the Default database prarameters section, I changed the Base filter to mx_entrytype=MX_PERSON. All the entries still show up, but only MX_PERSON entries will show details.
My updated guess is that we would needs some sort of custom code to hide the other stuff. If you're a Java programmer, see if you can find the old Virtual View class / configuration. That might give you some leads.
