Virtual space teleconferencing is a promising application field for networked virtual environments.

We confirmed that the system can serve up to 14 sites using multi-modal interaction without significant latency in operation from summational experiments. Then, introducing some assumptions to the results, we have proposed processing model of the system. The results of model could describe the experimental results and we could indicate roughy estimated system capacity to realize a requaied system performance.
