Web standards are great, and they are growing in capability and sophistication. Yet nowhere in the proposed specifications will you find local file access. Will these types of features eventually find their way into standards and browsers?

But how long will that take? Part of the reason we are seeing the web standards expand to include more functionality, is because users are demanding more compelling interfaces, and ultimately experiences. These demands result in application requirements that were not originally envisioned with the previous specifications. The interesting paradox that emerges is that it is much harder to differentiate yourself on user experience if everybody is using the same standards.

These plug-ins are not constrained by the standards process, and are free to innovate as fast as the market allows. In the case of the Flash Player, that has been roughly one iteration every year, that is broadly distributed and nearly ubiquitous in about one year after that. Does that mean you have to go all in on Flash?

In these two examples we have used web standards to build the user interface and drive the core application logic. We have extended those web standards with content running in the Flash Player to provide innovative new features such as local file access. And we have even leveraged the native browser implementation to perform image encoding where we would have had problems scaling in both JavaScript and ActionScript.

The moral is simply, use the right tool for the job. Download the source code for these examples to add local file access to your toolbox.
