Virtual World Intranets… When?

I was reading a post Written by Wagner James Au where it states that the latest trend is a corporate-controlled, business-centric virtual world architected for internal use only– call it the intranet metaverse.

• For Sun’s it’s MPK20, a “a virtual 3D environment in which employees can accomplish their real work, share documents, and meet with colleagues using natural voice communication.”
• In IBM’s case, it’s a rough-and-ready 3D environment created by their Innovate Quick team.
• In Cisco’s case, they are using Second Life for business-to-business communications.

But for smaller companies willing to beta test these new types of environments, there is nothing out there.

The question: When will a Second Life or one of its notable competitors, including Active Worlds and There will create an enterprise, secured, easy to use and bandwidth conscious tool for smaller companies to start deploying/testing?
