Thanks for the reminder.  I was about to send one myself to see if there was a chosen path.

Jim/Bill/others who have mentioned this;
   Just wanted to drop a friendly reminder that I'm waiting on direction
between these two options. I can quickly roll a trunk or 2.2 patch for
either of these if there is consensus for either mechanism.

Both will allow for taking a server offline after bleeding traffic away
by means of sending only existing sessions to said server. The
difference is in approach:
48841    Allowing zero as lbfactor tweaks the math a bit for the lbmethods
51247    Adds a Route-Only radio box to balancer manager and a constant
in the code to recognize the change
