> One warning about extremely large views is that at some point you will run into floating-point rounding errors, since AppKit and CoreGraphics coords are 32-bit floats and have only 24 bits of precision. Still, that should get you to millions of pixels before the coords stop being pixel-accurate.

64-bit AppKit is much better in this regard than 32-bit.  If memory serves, it lets you reliably operate NSScrollViews over dimensions in the billions.
