Integration with POS Systems

I would love to switch over to Surecart but the one thing that is holding me back is one integration. Many of my clients run an online store and a physical store. Most use Square or Lightspeed. It would be great if not only could you use the payment option BUT also sync products and inventory in regular intervals. Lightspeed syncs at a minimum of 1 minute (but can be increased) and Square syncs every 15 minutes. Seeing this integration would have me switch in a heartbeat.
