Hello I am comparing MapPoint Web Service and Mapquest Service and I wanted to know if MapPoint Web Service offered a Local Spatial Search Server? Mapquest offers this service, but I want to go with MWS if this feature is offered. The Local Spatial Search Server (LSSS) allows Advantage API users to search their
own databases without first uploading database information to MapQuest servers.
The LSSS is especially beneficial in cases where databases are so large (one million
or more records) that it's impractical to upload them to MapQuest servers. The
LSSS is also beneficial in situations involving highly sensitive data or data that is
updated very frequently, such as hotel data that is updated daily. Since LSSS allows
databases to reside locally instead of on MapQuest servers, users can utilize standard
database APIs such as ODBC, JDBC, OLEDB, etc. to perform normal database
searches.

You can do your proximity searches locally and just get maps back from MWS, here's a link that shows you how
