Sparky,
I think the real difference between the 66 blocks and patch panels is the user's access. 66 blocks are hard wired at the cross connect. One uses short CAT5 patch cords for the same purpose between two patch panels. With patch panel jack labelling, one can "plug and play" a network hub and other equipment.
The wall jack homeruns are punched down with the basic punch tool using a 110 bit. The setup is capable of the same flexibility as the Leviton Structured Media Center.
A big part of this is whether the client is (or thinks he is) hands on. The more likely the system is to evolve with new whiz bang hardware being brought home from CompUSA or the like, the more useful the patch panel will be.
