I have a site where I provide specially configured screens to fit the limited abilities of PDA's.  I am monitoring access with oContext:getRemoteBrowser() to see if there is a way to determine what is calling so that I can route the request to the appropriate responce function.  So far, I have these three values.  If you know of others, or if you see a better way to detect site access by a PDA, I would like to know about it.
