What you want is not that difficult at all over serial or a network 
connection (ppp over serial or ethernet). Serial - open serial connection
to tivo (Bash enabled!!) and send text2osd "Text to
display"CR_LF. 
Network - A little more complicated but simplisticly open a socket to 
port 23 (telnet) and pass text2osd "Text to display"CR_LF. then
in both 
cases close the connection.
