u should integrate bitshares checkout

see https://bitsharestalk.org/index.php?topic=11840.0

Say someone from around the world wants to by my widget with bitGLD.  I'm willing to accept bitGLD.  If my account has the name "myaccount" how do I know when the customer pays? 

With bitcoin, I would just give the customer their own address.  What should I do with bitshares?  Should I have them pay sale1.myaccount?  Would I need to register the sub account.
