Well, source code would be really nice... :)

What filter did you use? Kalmans?

Well, have you seen the AiLive demo? Take a look. In truth you dont need that much to get really to 6DOF. Problem is both the acelerometer and gyroscope are way too sensitive and error cumulating.
All you really need is a filter (most advice Kalman), and eventual recalibration when IR comes to use.

I had this simple idea, where you use the Wiimote, MotionPlus, the regular sensor on tv, and add another in the back of the room, that way you get IR recalibration every time, even with your hand(wiimote) behind you.

Err... Actually, the so called "sensor bar", wich is really a sender of IR, the Wiimote that is the receiving end.
But you're not quuuuite right. There are not only 2 points, actually there are 10! Five on one side, five on the other,
and those 5 leds (at each side) are not pointed all to front, only the 2 first leds(counting from the center of the sensor) are straight, the other 3 have different inclinations, they point outwards the sensor. I think the fact that they used 10 and pointed them outwards is to make a more ample field with stronger IR sign.
If you want to get that much accuracy, just put 5 more leds on the bottom of your TV, But I dont know if that will make difference to the regular wii driver.. Think you'll have to code. :)

I've been through the same, until meet some guys on wiiurself. Initially the'll tell you to use Kalman filter. But somehow I bumped into a very interesting paper describing Fusion filter for IMU(acell + gyros).
Got some very good material. give me a call: [email protected] (emal, msn,gtalk, skype).

Luck to you.
