Where am I - Roadmap

One thing I want to clear:
All my work is goin in the way of "syncing Magento TO Checkout App"...meaning my codes will not be as useful for those who already work on Checkout as for those who work on Magento and just want to add POS like me.

Concept is, sync tax, customers, products, stock and orders.
syncing orders will run the customers sync codes along the process to successfully assign the customer to the synced product with updated shipping addresses.
I already implemented the tax sync, but for me, in Egypt, we have only sales tax of 10%, no tax regions or any other special or compound rates...So I only implemented syncing the tax rate as a tax group in Checkout.

I am currently in the middle of coding the simple products sync.
The plan is to successfully implement :
-Customers sync/detect changes and update (done)
-Tax rates sync (done)
-Sync orders (partially done-without products or amounts)
-Sku, name, prices, cost, tax assigned for simple products(in progress)
-Sync stock to update inventory total costs and ledger
-Use of variations to sync configurable products and their associated simple products
-Sync stock back to Magento
-Automate these actions somehow, like with cron jobs or trigger after event
-Create a kind of log of each process/sync done for revising and error handling/fixing situations

I really am not finding hard time coding, and I really encourage people to start working with me on this module because in 10 days I am 30% done of what I need, so this is promising.
I also want to clear out that since I'm not just developing this for the community but first of all solve my work case. Then, not all features can be implemented in this module by me since I don't have the time, and I don't have the case to work on.

Maybe we can move this project on to bazaar or other similar project management solutions
