Dual monitor with OpenGL ?

Ops, my litte baby put her hands on the keyborad when i was typing, lets again.

You now a portable way ( my be a library ) the provides dual ou multiple monitors with OpenGL ( ARB must think about ). I’m developing a aplication ( a server ) that must map some events in some monitors ( at the moment 4 ) at same time. It’s a sercurity system and must be on full screen not windowed.
