This means the actual 'mods' are different to those provided by the mod authors. We can make tweaks and edits to files in the mod after it is 'installed' and then use those files in the modded game because MO stores the extracted mods away from the 'data' folder. Since the entire structure of NMM's and MO's 'profiles' are based on different methods I think it will be a very difficult task to get MO's profiles to install an identical copy onto someone else's computer.

I know in the past it would blindly sort the load order into a semi-random mess every time I installed a mod without notification or question, and I assume this is still the case today. Finally, I don't see any mention that Nexus Mod Manager has any intelligence in how it sorts the load order. Users must reinstall all mods (and it sounds as if 'reinstalling' also means redownloading every mod from Nexus), which means all customizations are deleted. The new 'virtualization system' sounds like Mod Organizer on the surface, but it's implemented with symbolic links in the Skyrim/Data folder back to Nexus Mod Manager's mods folder. I don't see any reason to migrate to Nexus Mod Manager for several reasons. If Nexus is allowing automated installations with Nexus Mod Manager, it seems the logical next step is to support profile sharing in Mod Organizer and share the STEP Core and STEP Extended profiles.

It'll be interesting to find out whether the license terms/terms of use is a Nexus Mod Manager exclusive, though. I read it more as Nexus is trying to play catch up with the Mod Organizer combined with various cloud services, but Nexus seems to be opening the door for automated mod installations with the profile sharing feature.
