i think for bricks and mortor business it will be tougher to incorporate and pursude them, even for online business it can be tough to start accepting bitcoins as although the payment services are improving, still none are on par with other large, legacy, card payment providers....hence, the tech is still to be made...for example what EPOS system will a shop install to accept bitcoins
??
Just in case you didn't see this (a bar accepting BTC with BitPay)
