I have to say I'm very excited for this. In my use case, when I want to get into rig manager (and I often do), it's a very laborious process of getting the Kemper near to my PC, getting it wired up and then playing on the PC - spinning back and forth between screen/kemper/speaker. Then taking it all out and moving it back afterwards. This is same issue I have for almost all gear that needs connected to a PC, but it's especially a pain when the pieces of gear are so fully featured that they suit a PC editor - e.g. the HX Effects I use.
It's actually things like the above that make me think I should really just get a laptop so I can move it to the gear... but now I can hopefully just edit on the iPad!
I realise I'm probably not like most that already have their gear near their PC, or have a laptop, but for me this will be a very very welcome feature. Imagine also the possible benefits of being able to surface any of the features in any way they wish in the GUI!
Colour me impressed.
