Paul created a 2.6.26 patch which I've been testing with excellent  
results in Fedora 9. Local (lo and ethN) labeled networking is more  
reliable than the IPSec equivalent and does not have the IPSec SA  
creation latency. I'll push this to a larger set of developers and  
testers next week and report any issues.
