There are a couple requests we have seen that sounded useful to us.  These
are a few of the things we have planned for lsvpd.

Add a way to see if a device has an LED and store this information somewhere
in each device.

Create SCSI_fill templates for SATA devices

Look into placing each Component's DataItem into a vector, so that end
consumers can simply iterate over the vector.

A long term goal of ours is to move all of the logic we use to collect VPD 
from the device-tree into HAL so that it can display this information and
so that lsvpd can move to simply being a front end for HAL rather than
maintaining much of the same information in parallel.
