latest svn from sf.net tomorrow and give it a go. Thanks again for
looking into making these additions.
Also, I will be switching from Cable to FiOS (FINALLY) in the next
couple weeks. I don't anticipate much down time for the Development
Oracle DB, but if you have any connection problems let me know.
