[Q] removing stock apps correctly (busybox and terminal emulator) topic

Alright, so checking up the system folder with root explorer I noticed that there are several applications related to the stock music player.
I can't just simply remove these "apks", right? Pretty certain there'd be leftovers of this app somewhere.
So, I realize, there's no "uninstall" script for the music app, but I was wondering, what is the most correct way to delete music application?
Simple doing this won't cut it, right?

Code:

---

su
cd system/app
mount -o rw,remount /system
rm -r MusicCommonUtility
rm -rMusicLiveShare2.apk
rm -rMusicPlayerWT.apk
mount -o remount,ro /system

[Q] Run Multiple Instances of Android Emulator that can Connect to Wi-Fi topic

I would like to know if it is possible to run multiple instances of an android emulator so that I can run multiple instances of the same application. The application needs to connect to the internet so a wi-fi connection would need to be available. In the Virtual Machines I have attempted to use I have not found one that allows a wi-fi connection to be used. Is it possible to either run multiple instances without a Virtual Machine or is there a Virtual Machine product that allows me to connect to wi-fi connection?
