My plans for Sparkle have changed quite a bit because of a new development.
I am now working for Apple in the QuickTime team. One negative aspect of 
this is that I can now no longer be as free as I was with talk of what I'll
be doing next. However there are positive aspects---what I am doing will get 
into QuickTime at some point and benefit everyone directly, and I can do 
rather more because I have access to QT souurces and undocumented functionality.

Apple have said they are happy for me to continue to work on Sparkle and 
release it for free. I plan to continue to do so. However the direction of 
Sparkle will probably change. I'm spending most of my time (on work and 
off) involved with my QT work and most of the ideas I had for future Sparkle 
MPEG support and performance improvements will ne put into the QT code. 
However there remain all sorts of areas of digital video that I'm interested 
in but that I'm not dealing with through Apple, and those will be added to 
Sparkle as I find time.

Many people mail me asking about future plans. In an attempt to save 
everyone's time, let me state what I know here.

Audio support will be added ASAP. That and issues related to it are the 
most important item now on my agenda.
Applescript support will dribble in as I feel a need to take a break from 
the complexities of dealing with MPEG.
I would like to start playing with rate-limited MPEG encoding, but that's 
complex stuff to get good results, so I can't suggest when I'll have 
something useful. However I have some ideas for starting right away.
Support for other small issues (for example showing previews when opening 
files) will come in bits and pieces.

These are the large goals. Many small things will be added simply as part 
of the code cleanup. If you need something added that you imagine is 
pretty trivial, mail me. It may be I can add it in a few hours and help 
you, and it may be something I wouldn't otherwise think of.
