-The openmoko app, tangogps, introduced me to a new GPS concept - Horizontal/Vertial Dilution of Precision. A location record will store the V-DOP/H-DOP value to get an accuracy estimate. A high VDOP means a low accuracy so take a larger area and low confidence as the object's location.

-Distributed. Each IceCondor installation (node) uses a distributed hash table to store location records. Nodes can be added to the network easily and once added, its data is searchable by any other node. Using a DHT for storage would loose the benefits of postGIS for lat/long queries.
