With Lua being the recommended scripting language for FreeSWITCH, this seems an excellent way to work with Couch.
For those that have the LuaRocks package manager installed, it's a simple 'luarocks install luchia' to install.
I'm interested in exploring CouchDB as the datastore for a distributed, fault tolerant voicemail system -- I think it's attachment feature and bi-directional synchronization are well suited for the task.
