Yeah, I'm using them together. Ipac2 and plunger kit work together without any issues.
I had the Ipac before I got the plunger kit and still prefer using it because of it's shift function.
Also, this way I had plenty of space left for my latest addition: An transparent Comptetition Pro for Baby Pacman. Used to have one of those... a long time ago. Boy, I'm getting old.
Edit: Oh, about your question. The Ipac emulates an keyboard and is fully programmable. You can build a button schematic in an editor and assign single or multiple key presses to it.
One key you can assign as shift key - best don't use a flipper button or magnasave button for this.
The nanotech kit is a game controller. You need extra software if you want it to act like a keyboard.
