Hi David, >> You say Pepperwhite Street is agnostic when used as a server. Hmmm. So... do I take it you are installing an ActiveX plugin in IE to accomplish this over the Internet? I'm not finding any info about this on their site or in the eval that I just installed. My client provides the customers with a hosted solution so running off a LAN is not an option, AFAIK. << What I meant by "agnostic" is that you can write (or use) a web service that employs the ActiveX control (not IE, I think, because you have no good way to reference the map data which would be on the server -- IE cannot consume a web service by itself). My assumption is that they have a mechanism to convert map data (images) to SOAP, so that it may be consumed remotely, by a "smart client" application. Since it is LBS, the only place the maps need be displayed, if I understand what needs be done, is on the application that is running at the server? That's where the use want the map, not in the vehicle. So, while PepperWhite advertises a web service (and you are right, there is no info on how that is done), we don't need a web service, only a Windows application. If you want to use the maps in the vehicle, then the web service would come into play (but this is not what I'd do, even there). Personally, I'd just write an application in the vehicle that displays the vehicle location on the map, a la MapPoint.
