The problem with ION is that there is no really useful modularity in 
there yet... it's a successful base operating system, the "big IOS 
process", and the CDP daemon.  The interesting bit "split the big IOS 
process into individual processes for each 'IOS process' functionality" 
was never done.

*Useful* modularity would have been "oh, security bug in BGP?  patch
bgpd, restart bgpd, go ahead".  This is what we have been waiting for.

The idea was good, the start was good, then there was no real progress
for 10 years, complete lack of adoption and support from the other 
BUs, and I'm fairly sure it's dead now.
