Sure, obviously you understand your network much better than I.
I just wanted to be sure that you really needed to do this - which
as you would notice is quite slow. Obviously you do and its all good.
I am glad to hear that the IPaddr2 script is working well for you.
It has been something that has been needed for a while but was only
recently added to the tree. If you have any problems with/ improvements
for it, please send them send them along to the linux-ha-dev mailing
list[1].
