+* provide support for non-hardwired (ie loadable) converters.
+
+  Q: What is a converter? Is this an implementation detail?
+  A: Not an implementation detail but a way to extend the engine
+  to convert more data types. Currently we have fixed set that is 
+  expanded on occasion (ie includes primitive types + File). Instead
+  of spreading converting code through out tasks it can be centralized 
+  into one component and used by engine. This becomes particularly

+
+[DISC] Ant's goals
+------------------
+
 * make it possible to reuse taskengine for other things. ie
   Installshield type app, Peter's cron-server and other task based
   operations. 
 
- * provide support for non-hardwired (ie loadable) low-level 
- components (mappers/itemset-filters/converters). Allow them to be 
- loaded in either global or a new classloader.
+* provide support for CJAN
+
+  Q: In what way?
+  A: Probably by supplying a set of tasks that download versioned 
+  binaries and their associated dependencies, caching the downloads
+  in a known place and updating binaries when required. ("When required"
+  being indicated by a change in property values).
+
+[DISC] class loading
+--------------------
 
  * force resolution of classes on loading to identify classloader 
  issues early. (At least in global classloader).
 
+* Ignore any classes contained in the damned ext dirs of a JVM - possibly by launching
+  with something like jar -Djava.ext.dir=foo -jar ant.jar
+
+[DISC] workspace/subbuild issues
+--------------------------------
+
 * create the concept of workspace so that projects can be built in a
   DAG and thus enable projects like catalina/tomcat to have an easy
   build process. It also helps CJAN to a lesser degree and would
   partially solve the JARs in CVS thing.
