[Badr Hack&Invent <badr@xxxxxxxxxxxxxx>]

Hi Wayne, 

Did you have a chance to give a look at this patch?
>From our side we are using it almost a year now, it works fine. 

Else, I don't know if an equivalent function is now under going in the
version 6?
If so, I will be glad to help in testing. 

Regards, 

Badr
