NBM 3.8.4 has a new feature that can do session fail-over in a Layer 4
Has anyone implemented this?

My customer currently uses NBM 3.8.3 and they'll hesitate to be the first
one implementing this feature.

Customer envioronment:
- L4 in front of a bunch of NBM 3.8 (of same tree)
- they use forward proxy with HTML SSL Authentication only, no Novell Client
or Client Trust anywhere.
