Abstract: In this paper we describe LiveTalk, a framework for Collaborative
Browser-based Replicated-Computation applications. LiveTalk permits
multiple users separated across the wide area to interact with separate
copies of a single application, sharing a single virtual workspace,
using very little network bandwidth. LiveTalk features an integrated
browser-based programming environment with native graphics and live
evaluation, an integrated, pluggable web server, and a simple messaging
service that serves to coordinate activity on shared application
sessions, and provides for multiple mutually-isolated sessions. The
first use case for LiveTalk is collaborative big-data visualizations
running on thin-client devices such as cellular phones, tablets, and
netbooks. These applications form part of a new class of application
where the distributed cloud is leveraged to provide low latency,
high-bandwidth access to geographically disparate users while
maintaining the feel of immediacy associated with local computation. The
primary motivation of this work is to permit low latency collaborative
applications to be built quickly and easily, while requiring no setup
for use by the end-user.
