I use EQMOD (an ASCOM driver for a HEQ5/EQ6). It supports a joystick for controlling a mount. To use a Wiimote, we need two additional software
1) GlovePIE - a windows program that can talk with Wiimote and control the computer from a wiimote.
2) PPjoy - a virtual joystick program
Then I wrote a short script and set parameters in GlovePIE. Finally, EQMOD can recognize the Wiimote.
I don't have a EQ mount now but tried it using a EQMOD simulator. You can control slew direction, slew rate from buttons in a Wiimote. The coolest thing is that you can control the mount by tilting the wiimote

Please see the following movie clip I took. The computer also tells the slewing direction (North South East West) COOL
