If written, they would both allow for a title manager to he installed without Cubic Ninja or PBT-CFW through MSET. The network spoofing allows for a .CIA to be sent over your network to the 3DS after targeted through its IP. That is difficult to implement, so nop90 said he'd be looking into another method, leaving that on the back burner. The other method is a silent install. From what I understand, .CIA can not be installed directly from ARM9, but CAN be pointed at (Root SD with something like installme.CIA prewritten.) and installed as some of the services start at boot.
