+   * notes on discovery service
+   * 1. need to allow multiple discovery source urls.
+   * 2. user interface to add/control list of urls in preferences
+   * notes on wsclient discovery
+   * 1. need a classpath property with list of additional plugin directories
+   * 2. optional config to cite specific bindings between class name and Abstract service name.
+   * 3. precedence for automatic discovery by using getAbstractName for WSClient - user added plugins override default plugins ?
+   * notes on wsclient gui
+   * code for gui attachment now moved to wsclient implementation. Needs more abstraction but approach seems to work.
+   * is it possible to 'generalise' the data retrieval calls further ? current methods are very specific (gatherForMSA or gatherForSeqOrMsaSecStrPred), new methods for conservation (group or alignment), treecalc (aligned profile), seqannot (sequences selected from dataset, annotation back to dataset).
