from E FAQ - e-speak sounds more and more like PB (although it did use XML
IIRC).
6.5. How does E relate to other efforts such as e-speak, EROS, and Mozart?
E is a language and infrastructure for secure distributed applications;
e-speak provides only the infrastructure. Both E and e-speak use capability
mechanisms for access control, while e-speak also has mechanisms for naming
and discovery. Both E and e-speak have trusted code that mediates requests,
allowing a degree of manageability not provided by systems that don't
mediate, such as Jini. Unlike E, e-speak is language independent, having had
programming libraries for Java, Python, C++, and Perl (in various stages of
completeness) in addition to a version for document exchange programming in
XML. The E language makes security guarantees that e-speak cannot. For
example, an E program can be analyzed for capability confinement. [Alan Karp]
