Two key technological trends of the last few years have been the
emergence of handheld computational elements and the implementation of
practical wireless communication networks.  These two changes have
made mobile computer systems feasible.  While there has been much
research interest devoted to mobile computer issues, such systems have
not yet been commercially successful.  This has been ascribed to the
lack of a ``killer mobile app.''  We believe that the support of video
on mobile systems will indeed make possible many new interesting
applications.

However, providing mobile video is a non-trivial task, and much work
needs to be done before practical systems are widely available.  In
this short note we address the issue of mobile multimedia from a
practitioner's perspective. We note what software and hardware are
currently available in the market in support of mobile multimedia, and
point out some of their deficiencies.  We also discuss some of the
communication and data management research issues that need to be
tackled in order to address said deficiencies. Exploring these
research issues is the focus of our project.
