Hi Chuck!
If you are just wanting to be able to monitor the front panel from your PDA, you will be able to do so pretty easily and without any installations on your PDA. To do so, in the Web Publishing Tool, set the front panel to "monitor" or "snapshot" (not "embedded"). Then when you view it on the PDA it will be just like a normal webpage.
However, you will not be able to control the front panel (by setting it to "embedded" in the Web Publishing Tool) from your PDA. This requires the LabVIEW Run-time Engine, which PDA does not support because of the ActiveX controls. To be able to control (communicate with) your VI, you will need to implement to separate VIs. The actual VI running on the host PC, and one for the PDA. The two VIs can communicate via TCP communication, which will enable you to read and write values between the two VIs.
For more information, please read this KnowledgeBase:
How Can I Communicate Between My PDA Device and a PC using LabVIEW?
