Not by me. I *did* however question its application :

Symmetric ?   That to me means its disqualified.

*You* say that thats not your stance , but when I than ask what that stance 
is you don't want to tell ?   Thats odd ...

Weaknesses that are equal or surpass that of a symmetric encryption ?

And Nuno, I've been *trying* to compare the security of the usage of the 
encryption *keys*.  Can you stay on that subject ?

And to re-re-re-repeat myself :

[quote]
Just think of what could happen when one of both parties "looses"
their symmetric key ?   And just assume that they do not realise
that it has happened.
[/quote]

I'm *still* missing an answer to this question. :-(

Or, bluntly said: I'm getting the feeling you want to ignore the, to me, 
obvious.

You may do that ofcourse, but you're getting tiresome.  You want to put your 
POV (stance?) forward and have me respond to it ?  Than I expect the same 
from you.
