Kolcun also mentioned a situation where the GSA invited comments on its FedRamp project. It asked companies or individuals to upload their comments to Google Docs, he said. Microsoft was concerned about rights that Google might have to the documents. Microsoft complained to the GSA and was allowed to submit its comments using its Excel program instead, Kolcun said.

Google said it doesn't own data that people upload into its systems and pointed to , which deals mainly with how Google handles users' personal information, such as their name and email address.

In 2009, Google had to correct a bug that inadvertently shared some Google Docs with people even if the author hadn't shared them. The sharing was limited to people the user had shared documents with previously.

Kolcun also pointed to delays in the deployment of Google Apps in Los Angeles, in part due to security concerns from the police department.

Google has had its share of successes, however. It won a contract to offer hosted e-mail to the GSA, which will become the first federal agency to use such a service. It has also won deals to offer Google Apps to agencies in Washington, D.C. and Orlando, Florida.
