Tony Li and I went through that process with AS_PATHLIMIT, which has  
received an early code-point assignment from the IANA. The idr wg  
chairs followed the prescribed process to the letter, which is perhaps  
where perceptions of trouble come from, but the process was not  
unreasonable or particularly difficult (and for AS_PATHLIMIT the  
chairs were prompt and efficient in doing their part).

(The reason AS_PATHLIMIT hasn't progressed since is a lack of follow- 
through from those who had expressed interest in the implementation;  
one of these days I will find time to enquire after progress from  
various people, and perhaps it can be resurrected. Note that I'm not  
suggesting that AS_PATHLIMIT is a magic bullet for anybody :-)
