Tug for taxi?

[shadesman89]

is there a possibility of implementing unpowered taxiing, for example having a tug pull the aircraft to gate instead of taxiing via engines, i know Heathrow, Schipol, Frankfurt and CDG all do this, is it planned for the future? or is it not viable

You mean a Taxibot ? Yes, it has been discussed a while ago, and it's surely a possible option for a future upgrade.
