Gaza monitors?

I noticed this small part of a much longer CBC story:

In Washington, President George W. Bush said the United States was working to support a meaningful ceasefire but an end to the attacks would require international monitoring of Hamas and arms smuggling into Gaza.

In his weekly radio address, Bush said the rocket attacks by the Palestinian militant group were an "act of terror" that showed Hamas was more interested in violence that governing Gaza.

"I urge all parties to pressure Hamas to turn away from terror and to support legitimate Palestinian leaders working for peace," Bush said.

"Another one-way ceasefire that leads to rocket attacks on Israel is not acceptable."

Is this just talk or does Bush have any information? Who would be the monitors? Unlike traditional peacekeeping there would be a serious element of peacemaking here -- and grave danger to the peacekeepers.
