how to support Restaurant Online Order Shopping Cart

[nhsoft]

hi, all

I want to do a  restaurant online order shopping cart.

Requiremetns:
1. multi-store support, each store has own food items and food categories
2. customers shared by all stores
3. can support to look for store by GMAP
4. if customer orders foods in more than one stores, need to split order-bill
5. store can monitor own order bill and process own order bill

Q1:from http://www.konakart.com/forum/index.php/topic,35.0.html, multi-store support has developed, but it has no timeline or roadmaps

Q3: can i add my KonaKart module to support gmap for stores search


I am newbie for KonaKart, someone could tell me how to start by KonaKart
