Yeah, it's a nogo at this time. There are custom roms that allow otg + charging so it could be implemented in a future update. The powered hubs don't send voltage down the host cable.
I use a nas drive to stream media over wifi, it works while charging. If your router has a usb port, try plugging a flash or hard drive in it. Then use a file explorer to stream or copy. Or from another computer on the same wifi set to share folders with the network.
