One of the problems at IETF comes from the need for rough consensus -  
often we can not get enough people to agree to the reduced scope -  
MSRP and XCAP might be an examples of that.  I do like to break things  
into as small as independent chunks as possible - I think that gets  
them finished sooner and it allows topics where one can't get  
consensus to get dropped. I realize it is apple pie, but one thing  
that could a help in RAI is people trying to make ideas smaller.

If draft-x gets published at RFC 1234, we can start on 1234bis the day  
1234 is published to add more to it. To make this successful we need  
the people sitting in the WG *not* to hum yes when asked if they would  
like to include the kitchen-sink option in draft-sip-super-simple. I  
note the RAI WGs almost always hum yes to taking on more work. We have  
the  combination of people who aren't going to do the work getting to  
hum yes that someone else should do the work combined with only  
volunteers with fairly erratic time commitments do the work. This  
combination is not an ideal combination for speedy work but it is what  
we have so we need to figure out how to make the best of it.

One of the hopes of Dispatch is that it could quickly spin up a way to  
get a small focused set of work done, such as config.
