it's interesting, though it's not really distributed rule engine.

it's just service oriented application that happens to ship rules in the
SOAP payload.  Said gave a demo of this for policy rules back in 2004.
Before that, said and I did this back in 2000 for mobile applications.  the
technique itself is quite straight forward. In the case of mobile
applications, the phone company has serverside rules, which apply to account
types/groups. On the phone side, a user defines their own rules. The two
sets of rules work in collaboration. The server owns their rules and the
users own the user level rules.

the neat part of the paper is that they are using the new features in
OO-Ruleml (aka production ruleml) URI feature to indicate a rule is remote.
for an SOA environment where a business process is broken into several
stages, it makes sense to allow the system to ship rules and reason over
data. The demo I created using JESS used JMS instead of HTTP.
