"The history footnote of the evening came from Benioff, who challenged Plattner to build SAP applications on the Salesforce.com platform. 'I want to figure out how to get SAP to build on our platform,' Benioff said. 'SAP needs to write its new apps on our platform, and I need to help him do that because there is no way he can figure that out...we will be in a war to get more developers on our platform.'

Plattner, who was writing software when Benioff was in grade school, wasn't biting, and became a bit exercised. He questioned whether Salesforce.com could keep thousands of on-demand service interfaces consistent as its platform grows and as customers write code to integrate with the platform."
