Previously (due to my ignorance and stupidity) AirX and MediaMote were unable to be installed together because they installed the same files in the same locations (files that I needed for both of them). App manager didn't like this, so you could only have one installed, but this has been fixed in these releases, so please, if you want to install both, following these steps...
1. Uninstall AirX or MediaMote from your tablet (Or nothing if you don't have either)
2. Install the Pexpect, then AirX from here.
3. Install MediaMote from here
MediaMote and AirX BOTH require Pexpect to be installed!!! If you only want to install one app, Pexpect must be installed no matter what!
And, as always Python and SSH must be installed on the tablet, and an SSH server must be installed on your Linux PC. (For Ubuntu users, use "sudo apt-get install openssh-server" to install an SSH server.)
You can see videos of each on Youtube!
