Requesting explanation of terms in CouchOne announcement

["Andrew Stuart (SuperCoders)" <an...@supercoders.com.au>]

Hello

The CouchOne announcement http://www.membase.com/merger-technology-vision 
  refers to the following terms but there's not much to explain them:

** user code execution across database nodes with scatter-gather support
** multi point triggers

Can someone refer me to explanations of these terms please?

The announcement also refers to indexing and query support - does this  
mean in the future CouchDB will include more traditional types of  
field oriented indexes?

Thanks
