The Kali Scheme project was started around 1995 by the Software Systems group at the NEC Research Institute. It is based upon Scheme 48.
Kali Scheme is a distributed implementation of Scheme that permits efficient transmission of higher-order objects such as closures and continuations. The integration of distributed communication facilities within a higher-order programming language engenders a number of new abstractions and paradigms for distributed computing. Among these are user-specified load-balancing and migration policies for threads, incrementally-linked distributed computations, and parameterized client-server applications. Kali Scheme supports concurrency and communication using first-class procedures and continuations. It integrates procedures and continuations into a message-based distributed framework that allows any Scheme object (including code vectors) to be sent and received in a message. Some of the applications and implementation techniques we have looked at using Kali Scheme include:
The active development branch can be found at the arch repository. It is recommened to use the stable version in the tarball.

Kali Scheme is described in Higher-Order Distributed Objects , ACM Transactions on Programming Languages and Systems, September 1995.
