John Cornyn is a Republican, not a Democrat - http://en.wikipedia.org/wiki/John_Cornyn. So it should be "Sen. John Cornyn (R-Texas)"

I encourage developers interested in working on such a replacement to take a look at Jakarta James ( http://jakarta.apache.org/james ).

James is a mail server project designed on top of the Jakarta Avalon Framework. It's a rapidly developing project that is designed to provide mail (SMTP, POP3, IMAP) and other essential services (i.e. NNTP). Speaking as a committer on this project I can tell you that I would welcome a new sub-project to develop iCalendar/vCal compatible services. I think it would be an extremely valuable addition to the project.
