Global Enterprises: How do you break down your IP addressing?

So I know everyone here is a fan of the cutesy 10.location.vlan.host scheme, but this only works when you have less than 256 sites. I'm curious to know about the ways global organizations, with hundreds of sites and multiple data centers, design their IP addressing scheme. Do you divide each geographic region into summaries? Do you break down IP address bocks for function (for less complex FW rules) or by location (for greater summarization)? A mix of both perhaps?
