Somewhat independently at least. We could set up a shared Google Drive space where we could drop drafts and finished entries for peer reviews, maybe set up some sort of chatroom where we could discuss in real-time... (Chatango works fairly well in that regard, accounts are free to make, but anons can use temp names if they wish)
Obviously I've been thinking a lot about the logistics of this xD
So I got a reply from chatango as I had contacted them about it and they said they can't reproduce it. They asked if you could please provide a bug report from your device so they can see the specifics of browser version+phone

So, you are tech support, and when your customer goes to your website and asks for live support, you want your smart phone or tablet to be notified you have a customer who wants help? Then you want to be able to chat with them?
"Chat" is live, interactive, and text-based. I think that's what you wanted.
Do you want a private channel for each customer? Or do you want all customers to be able to see each other's chats? That is an important issue.
Go to google and search for [free chat widget].

All great for RP, just saying. If you happen to have/make a chatango account, I've got a new RP account on there I just made which I'd be happy to use<3.
EDIT: Oh, and nice story<3. But I may be biased since it has my clan in it<3
