John, Using a statically linked version of cairo has helped us avoid many problems we've had in the past, related to wrong versions of cairo, dependency issues, etc. I avoids a cairo dependency on our libgdiplus package, and lets people use System.Drawing/WinForms without having to get other 3rd party stuff first.
If you're just worried about moving to 1.2, I do have a 1.2 update almost ready to check in, it should go into svn on Monday or Tuesday.
