Google Docs will soon be supporting uploads of up to 250MB, in all file types.
Google's Docs and Wave products are starting to look like a real collaboration solution, especially for loosely allied or ad-hoc teams which may not have any need for a real infrastructure of their own (I work with a shifting coalition of collaborators, in just such a scenario).
Does that mean that workflow or asset management within an organization is no longer necessary? I don't think so - I see Google as a better solution at the fringes, where organizations interact, and where the greatest communications difficulties typically are.
