Subject Re: Blue Sky Distance Collaboration System_Proposal Draft

Thanks! This certainly makes things more clear. While most of the  
people on this list are programming geeks, this is still somewhat  
outside of the mainstream area of expertise here, so expect to  
explain what BSDCS is over and over :-)

BTW I haven't found much usage of this term via Google, except for  
the BSDCS site.

A few more questions if I may:

* The proposal mentions that BSDCS is currently "an open source [..]  
project". Is there currently a place where people outside your team  
can access the source code? Among other things, providing access to  
source code may help you to find interested developers at Apache.

* This maybe redundant considering the previous question, but what  
license are you using at the moment? And also if you rely on any  
third-party open source packages, what license those packages require?
