Uneasiness with use of github for experimentation

[Curt Arnold]

While I'm bringing up contentious issues, use of github for a sandbox  
for developing significant modifications to CouchDB makes me uneasy.   
If I start something on github and accept contributions and ideas from  
other uses, I can't represent the eventual patch as my original work  
(as required by the CLA).  Also, it reduces the visibility (barring an  
explicit opt-in) of the development from the radar of the PMC and  
community.  Other ASF projects have created "sandboxes" in their SVN  
for experimental work and the threshold for commit access to the  
sandbox could be lower than the trunk (still would require CLA and an  
Apache account).  Any Apache committer could use Apache Labs, but  
since that is not developed with the oversight of the community that  
still needs a pass through the Incubator.  Having a sandbox or labs  
branch in the CouchDB SVN would provide a location for non-trunk  
development that is still under the oversight of the PMC and community.
