Sun Microsystems co-founder Scott McNealy has been asked to prepare a paper on open source software for the US government by the new Barack Obama administration.
As Sun is a strong advocate of open source - with its Solaris and Java operating systems freely available - McNealy's recommendations to the new government should not be a surprise.
McNealy told the BBC, "It is intuitively obvious that open source is more cost effective and productive than proprietary software.
"Open source does not require you to pay a penny to Microsoft or IBM or Oracle or any proprietary vendor."
McNealy told the BBC he wants to ensure the US government does not get "locked in" to one specific vendor or company.
"The government ought to mandate open source products based on open source reference implementations to improve security, get higher quality software, lower costs, higher reliability - all the benefits that come with open software," he said.
