offline comment on http://petelepage.com/blog/2012/04/thinking-about-the-offline-web/

Have you taken a look at the offline capabilities CouchDB provides? I gave a tech talk at Google in 2009, about ground computing and the benefits of local data: http://googlecode.blogspot.com/2009/09/chris-anderson-couchdb-relaxing-offline.html

Couch is being ported to many new implementations. For instance the new PouchDB syncs with CouchDB, and is built on IndexedDB for browser JavaScript https://github.com/mikeal/pouchdb

Also for iOS there is the lightweight TouchDB, which also syncs with CouchDB and uses SQLite for storage: https://github.com/couchbaselabs/TouchDB-iOS

The essence of the idea is that your data set should be the same no matter where you are (like the cloud) but stored locally (like a desktop). The endgame for this application architecture is independent apps (run offline and installed like desktop apps) that connect to the cloud when they want to share data or they are interested in a continuous data feed.

pretend code: launch the app, connects to couchbase, also some examples
var couchbase = require("couchbase"),
config = {
hosts : ["localhost:8091", "localhost:9000"],
bucket : "TapLibz",
password : "buzz-the-tower",
};
// would be neat to have default connection level
// options (place to set observe and expiration, etc)

Sync function runs validation and generates access() and channel() maps.
config.sync = function(doc, oldDoc, userCtx, secObj) {
if (doc.channel_id) {
// doc belongs to a channel
channel("ch-"+doc.channel_id);
// this document describes a channel
if (doc.channel_id == doc._id) {
// magic document, treat it carefully
if (oldDoc && oldDoc.owners.indexOf(userCtx.name) === -1) {
throw({unauthorized:"you are not a channel owner"});
