Google have admitted that there is a risk, similar to sending information by email, with their new Google Desktop 3. The problem lies with a new feasture ‘Search across Computers’ feature from the desktop app that transfers information from your PC back to Google servers in order to consolidate information and allow you to search for related information across more than one PC (presumably you would ibly enable this for searching across your own machines in your own enterprise).
Gartner have stated that “the mere transport (of data) outside the enterprise will represent an unacceptable security risk to many enterprises”.
