Remember, any U.S. veteran can get the actual System Access software for 
free.
SATOGO is very useful because it is taged to you, not your computer.  That 
means if you are sitting at a windows computer with sound and an Internet 
connection, you can make that machine talk, until you reboot it.  Then it 
returns to the machine it was, until you make it in to an accessible machine 
again.  Very handy if you are travelling over the Holidays.
