CouchDB itself scales quite well as far as the size of the DB is concerned (especially in the numbers of files you are talking about). It also scales well for numbers of synchronous users/clients, though if needed you can look at BigCouch for increased scalability as far as that is concerned I think (you can create a couch in the cloud). If documents or attachments are relatively stable (not being changed excessively often--like every couple of seconds), performance is quite high. Of course, your application will need to be built to scale well--check out the CouchDB guide online for a starter on how couch (and your app) can scale: http://guide.couchdb.org/draft/scaling.html.
