Not really. The miniRouter is designed to plug into the Raspberry Pi's header, there isn't an easy way to add more pumps unless you get a full router board, which can handle 15 pumps. We'll make these available if our Kickstarter funds.
In theory. The hardware is not limited to prevent this, but there is no software written to make this happen. We can't guarantee that this will be something we address immediately, but maybe third-party developers can help us make it available sooner.
No. This is part of what our tooling funds go towards, and will be included in the built Bartendro 7 and 15. We want to make plastic/rubber caps that allow tubing to slip through, while covering the bottle openings. The tops cannot seal the bottles however, there will need to be a small vent hole so that when the pump begins pumping, we don't create negative pressure in the bottle.
The router and miniRouter boards will be made available individually when we get funded. They will likely be bundled with the high power 24V power supplies that are needed to drive the pumps. Dispensers (pumps + electronics) will also be available. We will do our best to offer these to you at the lowest prices possible.
