\title{TeX and the Interface} \begin{abstract} \TeX\ systems have been a cornerstone of research and academic publishing for a long time. Development of how it interfaces with different classes of user or potential user, however, has been uneven. Recent developments in other areas of text processing are opening up new opportunities for \TeX-based systems. Should \TeX\ development become involved in these areas, or should it be restricted to those areas where it has traditionally been a strong player? \end{abstract}
