Where can we see the total hashrate of the network? I can see the hashrate of my pool but I have no idea about the network hashrate...

If the hashrate is correct, maybe we can just extend the 90 coins block reward for longer (6 months or so) instead of increasing the block reward... Because if my calculation is correct, block reward will halve again in 13 days or so. If the new wallet is not out by then and the price stays the same, more miners will leave and the network might be in troubles...
