So who could the contenders be? Here are two extremely promising applications built on the Flash platform:

SlideRocket

SlideRocket is a rich Internet application, built on the Flash platform, that provides for every part of the presentation lifecycle. It integrates authoring, asset management, delivery and analytics tools into a single hosted environment that allows you to quickly create stunning presentations, intelligently manage your assets, securely share your slides, and measure the results.

There are already a number of companies that are striving to be the web-based presentation application of choice, including Google, Zoho and Empressr.

SlideRocket is the first online productivity application that embraces business level features such as collaboration, robust security, dynamic data binding and business integration with applications like Salesforce.com. SlideRocket aims to differentiate itself from other presentation products by including a community marketplace where content and services can be shared and transacted. SlideRocket also embraces the best of the Internet with features like asset tagging, web content mashups, embedded data services and seamless rich media support.

It’s absolutely one of the best presentation creation applications out there. And because it’s built on rich Internet application technologies you can add interactivity and create a cinematic experience that I haven’t seen done any where else.

SlideRocket has been designed from the ground up with extensibility and portability in mind as well. To this effect, third party developers will be able to build components into slideshows using the application’s APIs, creating compelling presentations.

Blist makes it easy for anyone to create private or collaborative databases.

Blist is not alone in the online database market. Zoho DB, DabbleDB and Trackvia are all web-based tools that provide users the ability to create and administer databases.

Although Blist’s simplicity makes it seem like you’re not dealing with anything more complicated than an online spreadsheet, the Blist user interface is actually hiding a complex relational database backend.

Unlike other online database systems, such as Zoho DB, using Blist doesn’t require the user to know SQL to use all it has to offer. This makes Blist great for users who need more than an Excel spreadsheet, but who don’t want to delve into the complexities of a database software application like Access.

Blist’s focus on making database creation and management a straightforward process, built on an always available, rich Internet application suggests it can fill a niche. Demand will prove the depth of such a niche, but if it grabs enough attention from people as regular users, it will become an extremely interesting prospect for acquisition.
