It won't be the the Next Big Thing if the network stays artificially limited to 7 transactions per second...
You wish you had 7 tx/s in the bitcoin network...
Even with the cancer satoshidice is, it's very far away from the 7 tx/s limit.
7 tx/s would mean 4200 tx's each 10 minute block.
To be fair, mobile payments through M-PESA in Kenya (a country with about 0.6% of the world's population), is choking on 270 transactions per second.
