In BCAP's website it states that the whole thing could be implemented in a couple years. In my opinion, if the DTCC continues pissing off microcap companies like they're doing now, the companies will either give up on the stock market, or look for a solution, that is: to BCAP's plan.
Because if BCAP clears transactions (and makes deals with other brokerages so microcap trades are done thru BCAP's system) our beloved Chinese POS plays would come back, without the threat of the DTCC. ;-)
