No it's not. It's very similar though. It's older code that's been used by someone to develop their own version. It is offered at scam sites in particular. See http://www.limewire.org/forum/showpo...45&postcount=2

As far as the preferences folder goes, I'm not sure what name it will have since I've never tried 360. But try steps 2 & 3 & swap the LW name with 360 & see if you find anything. You could also search manually, by looking at these directories:
C:/Documents And Settings/your_username/.limewire (or 360)

C:\My Documents\limewire (or 360)

C:\Documents and Settings\*yourusername*\Application Data\limewire (or 360)
BTW the application data folder will be invisible so you'd need to change view mode options to show all hidden files & folders.
