Sorry. No. Everything that kills my productivity while I am offline is a no-go. Reasons for being offline:
* I just don't want to (e.g. Distraction free working)
* I am on a train
* I am on a plane
* I am in a foreign country and 3G is far too expensive
* Mobile internet is still spotty
* My internet provider has DNS problems (happened last week)
* Street workers hit my internet cable
* Other strange circumstances called "life"
Also: Tabs within a page that is displayed in a browser that has tabs that is displayed on a desktop? Well, great. How about a vim split in that bash tab?
