The PDS version of BridgeView (or LabVIEW DSC) includes the application builder. This will allow you to build stand alone applications that can run on another machine. On the target machine you will need to have the run-time version of BV (or DSC) in order to have your tag engine work.
For the second question about setting up to communicate to a LON server. LabVIEW will support communication through OPC, DDE, Active X, Data Socket, as well as external comm methods like serial and GPIB. I'm not sure what problems you are experiencing with the LON manager DDE server, but using the DDE vi's in LV (or BV) you should be able to connect to a DDE server.
