\secA{Future developments} Here are lists of planned improvements and a wish-list of features that would be nice to include (but are not planned in the immediate future). Let me know if there are items not on these lists, or items on the list you would like prioritised. Planned developments: \begin{itemize} \item Parallelisation of the code, to improve speed particularly on multi-core machines. \item Better determination of the noise characteristics of spectral-line cubes, including understanding how the noise is generated and developing a model for it. \item Include more source analysis. Examples could be: shape information; measurements of HI mass; more variety of measurements of velocity width and profile. \item Provide some indication of the significance of the detection (\ie some S/N-like value). \item Improved ability to reject interference, possibly on the spectral shape of features. \item Ability to separate (de-blend) distinct sources that have been merged. \end{itemize} Wish-list: \begin{itemize} \item Incorporation of Swinburne's S2PLOT \footnote{\href{http://astronomy.swin.edu.au/s2plot/} {http://astronomy.swin.edu.au/s2plot/}} code for improved visualisation. \item Link to lists of possible counterparts (\eg via NED/SIMBAD/other VO tools?). \item On-line web service interface, so a user can upload a cube and get back a source-list. \item Embed \duchamp\ in a GUI, to move away from the text-based interaction. \end{itemize}
