Overall, while Vivo's audio/video streaming solution once nearly equaled that of RealNetworks' RealPlayer -- and it did so with the benefit to developers of not having to purchase a specialized server for delivering real-time multimedia content -- the lack of continued development will surely hinder Vivo's chances of continuing to be competitive.
Although RealPlayer easily takes the nod at this point for the reasons listed above and also because it sports a more advanced set of features, Vivo does merit considerable attention. Developers especially will want to take a close look at Vivo for the fact that is one of the few streaming technologies available that allows you to serve real-time multimedia content from a standard Web server.
Pros: Offered real-time A/V streaming without the need for specialized servers
Cons: Lacks many of RealPlayer's more advanced features, dated feature-set and interface, discontinued — no longer developed or supported
