web and computers...

One interesting tendency about the web these days is dramatic browser tech advancement.... just a mad idea, could this lead to practical self-applicability and/or developing the whole system in (or rather as) a browser?

And I do not mean things like Dan Ingalls' Lively Kernel, no. The idea is more of a standalone bare browser/server on hardware that can be useful both connected or not. this could include a proxy cache as store; booting from the web or local server (loading data to the cache), working with the data locally and posting changes when the system is on-line.... redefining the personal computer concept in terms generally associated with the web.

Some food for thought :)
