I was referring to the overall resources ie the huge amount of disk  
space often needed, the servers to collect it etc.. as for the actual  
routers resources I'll take your word for it as I can't see anyone  
using ip accounting for anything on a large scale anyway, it's hardly  
descriptive but I do find it handy in those times when you are on the  
spot and looking for a culprit who is chewing bandwidth, I guess it  
makes more sense to use ip route-cache flow and the output of a sh ip  
cache flow in that case if netflow truly is that much better on the  
routers resources, oh well learn something new every day :)
