+\subsection{\glspl{mTask}}
+The current \gls{mTask} engine for devices does not support \glspl{Task} in the
+sense that the \gls{C}-view it does. \glspl{Task} in the new system are are
+\CI{Main} objects with a program inside. A \gls{Task} runs periodically, on

+\subsection{\glspl{SDS}}
+\glspl{SDS} behave a little bit differently on an \gls{mTask} device than in
+the \gls{iTasks} system. In an \gls{iTasks} system, when the \gls{SDS} is
+updated, a broadcast to everyone in the system watching is made to notify them
+of an update. \glspl{SDS} on the device can update very often and the update
+might not be the final value it will get. Therefore a device must publish the
+\gls{SDS} explicitly to save bandwidth. This means that an extra function is
+added to the \CI{sds} class that adds the \CI{pub} function.

 The \glspl{mTask} are sent to the device in bytecode and are saved in the
 memory of the device. To compile the \gls{EDSL} code to bytecode, a view is
 added to the \gls{mTask}-system called \CI{ByteCode}. As shown in
