>>Sorry heres more:
>>I am allowing IPX,UDP,TCP/IP,Serial, and Modems for communication. I will be be passing objects as parameters from one client to another across whatever medium is available to the users. This app will be maintaining a realtime map of a region and the location of various company resources. ie Trucks, couriers, cars, and individual items. The application will have to be able to update/validate each client vs the other clients for reality checks in nearly realtime.
>> My major concern is that the objects are not able to be passed to a remote application as an object. For example say I have a truck on main street and that truck has delivered package #1 say I have an object oTruck that has information about truck #1. I want HQ to know that truck #1 has delivered and is now on main street. I have oTruck.location and oTruck.inventory (oTruck.inventory property is really another object) so from the remote client I want to simply pass an updated oTruck to the server application who will validate the in information and forward it on to ALL attached clients.

Why is it not a good thing? It seems like all your information is there ready for the using. Given that its a bad thing and at the risk of sounding like an XML detractor: What kind of security will I have using XML/text? Is there a canned method like ClassToXml() and back, VFP has TableToXML and back so I wouldn't be surprised. However, VFP handles strings way faster than VB so would this be a large time drain? I appreciate everyones time.
