Is SELinux leveling multi-level security?

LinuxSecurity.com: Just how much is security, especially in high-demand Government sectors, going to be driven and how is SELinux going to play a part?

This is a very interesting analysis on how SELinux has the opportunity to be so effective at locking down a system, it could devalue the current break up of security solutions. Interest in multi-level security in the intelligence and Defense agencies seems to be high right now, because it would allow analysts to access networks of multiple security levels with one machine. Now (so we hear) analysts may have two or three PCs in their office, one for each security level. The case he makes is that SELinux has the potential to negate these different levels and systems. Could SELinux have that kind of effect or are high-demand users still going to expect multiple systems?
