According to Adam Rubin:

Backman still expected to remain with Mets

The Mets have not been asked by any other organization for permission to speak with Wally Backman about a managerial vacancy.

This could confirm my suspicion that not only do the Mets not view Backman as a big league manager at this time, neither does anyone else.  We all know Backman's storied past both good and bad, but what is undeniable is that he most likely has more of a special place in the hearts of fans than he does in the minds of GM's.  I think he will eventually get there, but GM's are going to have to see a changed man and I am not sure they do yet.
