Ok, thanks for the pointer. I will just have to let the dust settle 
before any decision is actually made... I don't really see how to work 
the current implementation around the security constraints described. It 
seems a bit too much, but I'm seeing this from the casual developer 
seat, not that security conscious, I have to confess.

But I must say I'll push as hard as I can to allow for what I'm 
currently doing, as it seems like a fair request, which appears not to 
fit the paranoid mode always needed when implementing serious security. 
But I insist, there has to be a solution that works both ways, we may 
just have to let things evolve from ideas into usable frameworks to 
address each shortcoming in turn.

I am not knowledgeable of the bitfrost implications at all, so I can't 
propose solutions at this point, only ask questions :( .
