Adding lots of application servers isn't the hard part, generally (from what I've read... I have to admit I've never had to do more than the 'easy stuff'). The database is. How's Mnesia scale up? Where does it work well, and where does it not work so well?

If you find it difficult to scale up databases, try looking at CouchDB instead http://couchdb.apache.org/index.html
