I'm using XeLaTeX to take notes in class, and I am using a new section for each lecture. Since the lectures have different teachers, I'd like a small italic subtitle for each \section.
I'm using the article class.
How would I go about doing that?

Here's one possibility, using the titlesec package; before each \section, some commands can be used: \undefds suppresses previous dates and subtitles; \sectiondate{<text>} assigns <text> as the date for the following \section, and \sectionsubtitle{<text>} assigns <text> as the subtitle for the following \section.
Since titlesec was used, somre restrictions apply (See About memoir and titlesec incompatibility). The code:
\documentclass[article]{memoir}
\usepackage[margin=3cm]{geometry}% just for the example
\usepackage[T1]{fontenc}
\usepackage[explicit]{titlesec}
\usepackage{xcolor}
\usepackage{textcase}
\usepackage{lmodern}
\usepackage{lipsum}
\makeatletter
\newcommand*\nameundef[1]{%
\expandafter\let\csname #1\endcsname\@undefined}
\newcommand\sectiondatefont{\normalfont\sffamily\itshape\bfseries\Large}
\newcommand\sectionsubtitlefont{\normalfont\sffamily\LARGE}
\newcommand\sectiondate[1]{\def\@sectiondate{#1}}
\newcommand\sectionsubtitle[1]{\def\@sectionsubtitle{#1}}
\titleformat{\section}
{\normalfont\bfseries\huge\sffamily}{}{0em}
{\colorbox{gray}{%
\parbox[t]{\dimexpr\textwidth-2\fboxsep-2\fboxrule\relax}{%
\vspace*{1ex}%
\@ifundefined{@sectiondate}
{}{{\sectiondatefont\@sectiondate}\\*}%
\raggedright%
\textcolor{white}{\huge\MakeTextUppercase{#1}}%
\@ifundefined{@sectionsubtitle}
{}{\\*{\sectionsubtitlefont\@sectionsubtitle}}%
\vspace*{1ex}
}%
}%
}
\newcommand\undefds{%
\nameundef{@sectiondate}\nameundef{@sectionsubtitle}}
\makeatother
\begin{document}
\sectiondate{March 15, 2013}
\sectionsubtitle{Test Subtitle}
\section{Test Section With a Title Spanning Two Lines}
\lipsum[4]
\undefds
\section{Test Section}
\lipsum[4]
\undefds
\sectiondate{April 23, 2009}
\section{Another Test Section}
\lipsum[4]

\sectionsubtitle{Another Test Subtitle}

An image of the result:
Here is a solution using the titlesec package inspired by @egreg's comment.
The title text is indented by extra 1em.
For the first line, this extra indentation is cancelled by \hspace{-1em}.
With section number:
<-- -1em
1.1 The first line of title
the second line...
-----> 2em
Without section number:
<-- -1em
The first line of title
the second line...
--> 1em
Code:
\documentclass[final]{book}
\usepackage{lipsum}
\usepackage{titlesec}
\titleformat{name=\section}
{\normalfont\Large\bfseries}{\thesection}{2em}{\hspace{-1em}}{}
\titleformat{name=\section,numberless}
{\normalfont\Large\bfseries}{}{1em}{\hspace{-1em}}{}
\titleformat{name=\subsection}
{\normalfont\large\bfseries}{\thesubsection}{2em}{\hspace{-1em}}{}
\titleformat{name=\subsection,numberless}
{\normalfont\large\bfseries}{}{1em}{\hspace{-1em}}{}
\titleformat{name=\subsubsection}
{\normalfont\bfseries}{\thesubsubsection}{2em}{\hspace{-1em}}{}
\titleformat{name=\subsubsection,numberless}
{\normalfont\bfseries}{}{1em}{\hspace{-1em}}{}
\begin{document}
\section*{Very long section heading that takes two or more lines when it is typeset on page}
\subsection*{Very long section heading that takes two or more lines when it is typeset on page}
\subsubsection*{Very long section heading that takes two or more lines when it is typeset on page}
\lipsum

Best Answer
One problem with simply adding some formatted "teacher name" text after
\sectionis that nothing prevents a page break immediately after the teacher name. (By default, LaTeX ensures that a section heading is followed by at least two lines of text.) Therefore I would use the titlesec package and its ability to execute additional code after the section title has been typeset (but still within\section).(The blindtext package is only used to add some dummy text to the example.)
