Will Anonplus run in the background so a user can have webui run normally?

It may be possible with drag on the network, but it has never been tried on those devices.

The best answer we can offer is that currently no one here knows exactly what the capability of those devices are for the Anonplus network. We will learn going forward; it just takes one person to find a perfect answer and after that its about sharing details and building the shared knowledge.
