Demand IS faster than anyone can keep up with.  That's why your system is automated.  In fact it's right in the name and the single biggest fact touted in all of the press about Bitinstant.  The system used to be automated and in fact still is every so often when you have money.  So why are these issues so pervasive if Bitinstant isn't a Ponzi scheme?  It's a very simple matter: confirm customer money received, execute corresponding trade/deposit for customer.  Zipzap's API isn't having problems, and I have contacted them and they say their API hasn't changed in months.  That means that you should have no problem automating everything since you have no money problems, as Charlie repeatedly says.  So why do these issues exist?
