thats true what you say. But think in a financial way if you speak about exchanges. They have to earn money. What can they earn right now?
We can't support two exchanges!

Learn to walk before starting a marathon.
Don't try to get to the big exchanges as long as Zeit is unknown as it is.
Grow, become more public and than the exchanges will come to Zeit.
2-3 btc trade volume / day and than its getting interesting for the exchanges.
I'm  absolutely not against Zeitcoin indeed I realy hope that your dreams will come true.
