Any chance of have this block that allows us to see all of our patterns that are connected to the network, thus allowing us to place our patterns remotely rather than running to the machine, similar to AE2's interface terminal?

The ability to add speed upgrades to and/or configure connected crafters and/or importers/exporters/etc. from within the system would be nice too.

Having both a wireless pattern grid and a wireless interface grid would make automation much nicer, too.

Of course, having an interface grid would create UI problems unless you could label crafters, like AE (one of the most criminally underused features in that mod).

This has been implemented for v1.5.33 as the "Crafter Manager".

Will it work for other things that implement the API, like the Reborn Storage multi-block?

Yes
