Now to mashup the last two posts, Jeff Barr highlights the Cardbox application. Cardbox looks like a Win 32 semi-structured database application, akin to Mac OS's venerable Tindebrox, and a contemporary of the late, lamented HyperCard. As advertised, Cardbox has both remote scripting and plug-ins. Barr points out that the Cardbox extensibility has been hijacked to support S3 integration for internet backup of Cardbox databases and explicit inclusion of S3 objects.
