status of multipart requests / attachment replication

[Adam Kocoloski]

Hi devs, in COUCHDB-163 we enabled the replicator to download  
attachments without Base64 encoding.  We'd like to do the same for  
push replication / attachment uploads.

MIME multipart is one way to go about that.  Has anyone put in some  
work on that front?  are there other alternatives we should be  
thinking about?  Best,

Adam
