Funny enough it's been tried as a business concept, though under different circumstances. In the mid-90s a company called AngelCorp wanted to build a series of manned aircraft that could loiter at high altitudes for long periods of time to provide high speed internet access. This was shortly before DSL, CableModems, WIfi and T1/T3 connectivity at the workplace would pretty much saturate that market. Bad timing.
Scaled Composites built one ship, the Proteus, a beautiful, revolutionary aircraft that is still in use today for many other payload missions such as airborne laser testing. The Proteus was also the uncle of White Knight I, the mothership for SpaceShipOne.
The odd thing is, the AngelCorp website still exists, frozen in time.
With advances in battery propulsion and cheap UAV / drone guidance systems, it could be a workable thing for providing temporary access to remote regions.
