sounds neat. I went and had a look at ichiili.sourceforge.net but it does not
seem to have a lot in CVS that can be twiddled with at this stage.

cool. BTW you may want to have a look at jakarta-avalon-excalibur/monitor +
jakarta-avalon-phoenix/src/java/org/apache/avalon/phoenix/components/monitor
that does a similar thing. The excalibur classes are a generic monitoring
toolkit while the phoenix ones monitor deploy directorys and redeploy on
changes.
