I'm not sure how this fixes anything. The idea behind a standard packet size is 
that it makes doing any type of analytical attack on GNUnet much more 
difficult. 
If we could choose a random packet payload size (and it would have to be random 
to prevent traffic analysis) there is still a high chance that a 1500 byte 
packet could be chosen for sending, right? I personally like the idea of just 
'fixing' the queue mechanism as Christian suggested, but maybe that's not 
feasable.
