I think it is time for a further review and bulletin:

In Jun 2003 I produced a list of topics and commented on them in
December 2003
So now to the current state as I see it:

 a) Parser
    ------
    Little or no progress.  I have improved lexer and it is now
    compatible with loadable opcodes.

 b) Sound file library
    ------------------
    This is mainly done.  Some of the utilities (in particular dnoise)
    have not been converted yet

 c) Completion of Portaudio v19
    ---------------------------
    There have been major improvements here.  On Linux we have a
    working system with some concerns about performance.  On Windows
    Portaudio suffers from high latency, and at present the ASIO
    variant is not functional.  The mac is even more problematic as
    the pa_v19 port to OSX is far from done.

 d) Software bus
    ------------
    Designs have been floating about but I do not get a clear feeling
    on consensus.  The proposals have been mainly easy to code, so it
    is a policy issue

 e) Check mac build
    ---------------
    Thanks to steven and others there is progress here.  It is up to
    them to report.  No progress of integrating a Mac-like user
    interface onto the API (I think) but a simple command-line build
    works in delayed time.

 f) Check Windows build
    -------------------
    I think Michael has sthis under control now; I do not have the
    space to build on Windows now

 g) Reorganisation of opcodes
    -------------------------
    This needs review.  The code works, but I am not totally happy
    with the specification method for loading.  There is a suggestion
    that there should be a specified core, and the rest should be
    loadavle but there is no progress here

 h) separation of API
    -----------------
    I think this is progressing welll there are uncertainties about
    division into external/internal parts which needs more thought.

 j) MIDI
    ----
    Little or no progress has been made with PortMIDI; some older MIDI
    code is still working

 k) Simple build for Linux
    ----------------------
    Awaits software bus in part

 l) Making re-entrant
    -----------------
    Progress but needs a further push; there may be significant things
    to do here.
