Dataverse/Astral Realm questions

[Undersiej]

I have a strange question.

I plan on making my character a cyborg (involving use of the dataverse uplink item after I can purchase it).

Would I be able to be in the dataverse and elsewhere at the same time? I plan to be 'online' in the dataverse via his cybernetics and be in other places at the same time if that's possible, like Sergeant Major from Ghost in the Shell theoretically could if she could split her focus and do both at the same time (or at least connect without that damn cord).

Edit: Basically, it'd be like having an Uplink station or VR Helmet on the inside of your body and having to spit concentration to maintain efficient in either location. What would I need to purchase to make my idea work? Would I have to take a power to be able to be in both locations at once? Mutiple item purchases?

Second question not entirely related to the first. Would you be able to talk outside of the Spirit Realm while within the Spirit Realm? I mean carry on a conversation, not fight and such. Probably requires the eyes to be closed though.
