Scared you away as an individual user? Maybe what rPath is doing is actually a better fit for a different class of user. Dedicated, virtualized application deployments for specialized and controlled business needs is one obvious example. That's rpath's core market as a business. The virtual appliance building framework which is the focuse of this press release really isn't end-user hotness. rpath's previous creation, conary , is more directly useful for end users. You want a taste of that, try foresight linux and then get involved with that community as a developer or packager if you want to get familiar with rpath's developer oriented tech.
But more generally I think that the technologies rpath has put together make a really good fit for more than "virtual" appliances, they might make a lot of sense for actual appliances.. for dedicated hardware targets with prescribed usage scenarios..like computing appliances, personal gadgets, point of sell devices of all sorts, and or even perhaps netbooks. In the oncoming rush to market by several vendors to find the discount price point.. if netbooks end up being marketed more like appliances... more like cellphones...than general purpose computers... the way rpath's tech lets you put a distribution image together and roll updates for it might be appealing to netbook oems over the more traditional linux distribution models.
