The command line approach to executing commands was added for instances where maybe you have a desktop shortcut - it was never intended to fully control VoiceAttack. Most would simply create a plugin for VoiceAttack in order to control it directly- hence the reason there is no "port injection". See the help documentation section titled, 'VoiceAttack Plugins (for the truly mad)' (press F1 while VoiceAttack has focus).
In the coming year, I will be exploring alternatives to the Windows speech engine(s). Latency is the biggest hurdle, as a whole second for any amount of recognition isn't something an everyday VA user would tolerate. If you are looking for something with a bit more speed with Windows' speech engines, take a look at the 'Restricted Continuous Speech' and 'Continuous Speech' options for commands.
In regards to UAC, there really is no good reason (except for a very few, and especially not for games) for anybody to be running applications as an administrator. VA suggests this, because many inadvertently do run their applications as an administrator and promptly write in 'Why does VA not work with my game?'. The suggestion is then always to not run their game/app as an administrator, but running VA as an admin will get them by in a pinch.
Congrats on getting Whisper going - that's a nice skill to have. That said, I will suggest that you rephrase your post and remove the reference to the special olympics, as that is highly inappropriate. Thanks!
