How does it impact the development of B&C and the selling of shares? I guess you won't be able to start selling before you have the B&C block chain ready, so there would be development needed prior to receiving any funds at all.
The proposed (but not finalized) plan is sell BlockShares and then deliver them within 30 days as a blockchain asset so they are liquid. The network will be completed according to the 20 page design paper posted in the OP in the following months.
