interesting, thanks for sharing!

What else I could say, I am really deeply extremely ... (can't find 
other words) ... shocked they don't use SIGCOMP specs [ha ha!]! I 
remember some discussions when I said that usage of one well established 
compression algoritm will get it done in few hours (implementatio wise) 
than what IETF came up with in this regard. Sad but true, many IETF 
specs have no touch with reality...

Maybe I missed while quick reading, what are the "various /slight/ 
protocol violations" you spotted?
