When you want to both send and receive stdin/out to/from a command,  
you need to use popen3.

For example like this (untested):

     require "open3"

     Open3.popen3('"$DIALOG" -m select_photoset') do |stdin, stdout,  
stderr|
       stdin << plist; stdin.close
       res = PropertyList::load(stdout)
     end
