Hmm, off the top of my head that sounds like you'll expose a security 
vulnerability doing that. Unelevated data being passed to elevated process. 
You'll also want to pass a hash or something to verify the file is the correct 
file on the elevated (deferred) side.

Subject: [WiX-users] DTF managed custom action - temporary file

I want to use a temporary file to transfer data between my immediate custom 
action and my deferred custom action (Impersonate="no"). I use the method 
“Path.GetTempFileName()” to create a unique file in the immediate CA. The file 
will be created but the deferred CA cannot see this file. 

Where I have to place the file to get it working?
Or is there another solution to transfer the content of a complete own table?
