VERY URGENT : Mobile phone & computer connexion

Hi everybody ,
 
This question, I thing doesn’t have a lot to do with kannel, but may be
one of you has an answer.
 
I am developing a pacman game (flash or java), and I would like the user
to be able to play it with the mobile phone.
I explain, the game is on the screen of my computer, without keyboard,
anybody who would want to play pacman, can dial à phone number with the
mobile phone and play using the phones buttons.
 
Does anyone of you have a solution, a link or what ever can help me with
that !
 
Thanks
