Future Ideas
------------
save log messages to a ring buffer and then have DWR grab them and turn them
    into alert()s whenever engine.js is read. Only good for errors and warnings
    but could help in setting things up.
Create a wiki with help on error messages along with a link in error
Create a jdk 1.5 version of the collections code converter to get more type info
Create a batch send mechanism so a page can start by sending a set of remote
    calls all at the same time.
Add pluggable marshallers so we could do JSON or XML-RPC out the back end
use jdk5 annotations to pass comments to generated javascript interface so the
    the created javascript is documented (or maybe javacc and javadoc)
