That is not what I meant. Of course it is not an obstacle of getting code `in', 
but the
problem is in getting the code `out' or updated when there is time for a new 
revision.

When there is little or no documentation in the code saying which variable or 
piece of
code belongs where, then each time someone wants to change a bit of code has to 
reverse-
engineer what actually is going on. This can be very time-consuming. So I was 
not thinking
in terms of merging (although I am sure that Arnaldo will pick out bad code), 
but of keeping
the code changeable for a longer period and easier to update.

Don't get me wrong, I don't mean your code here, it is a general problem which 
I think we
should pay more attention to. And, as said, my ideas of keeping things separate 
may not be
the best possible solution, only one that I could think of at the moment.

|  Agree all the versions are a mess. I think it's worthwhile starting on

Hopefully there will be some IETF consolidation about rfc3448bis in December, 
then all this
could be reduced to one revision. 

Imagine -- 4 different developers and 3 different draft versions :(
