Avri: 
"..there is no multistakeholder model without governments,...."

Wolfgang:
I see four models
1. ICANN model (with governments in an advisory capacity)
2. WSIS model (with non-governmental stakeholders in a consultation process)
3. IGF model (all stakeholders on equal footing with no decision making capacity)
4. NetMundial model (all stakeholders on equal footing with limited decision making capacity)

RIRs and IETF are special cases, open to everybody but too Special.

Interesting experiences emerge in some countries at the national Level. 

Lets wait and see what Fadis "many little ICANNs" will produce. 

We are still in an early phase. There is no "BEST practice", but there is a growing number of "good practices".
