I am a little bit surprised that there has been hardly any response  
to the new framework setup. The WWDC meeting brought some great  
ideas, which we extensively discussed on the list. It was good to see  
some life back on the forum, and to see that people are still  
interested in further developing BioCocoa. I then started  
implementing some of the new ideas, more or less to compensate for my  
absence at WWDC, but also because I think they are good improvements.  
But after that it has been awfully quiet. Maybe people are on  
vacation, or just plain busy, that is very well possible.

That being said, has anyone had a chance to look at the updated  
project? Any comments, suggestions, ideas?

As I posted a few days ago, I think that adding the code for mutable  
sequences could be next. Also important is the transformation of  
existing code to use the NSData sequence object, instead of the
