Yes there was. And there's code in CVS towards that end. But that would 
not eliminate bjam. If I remember correctly the Jam language aprsing 
would still be implemented in the bjam executable and Scons would be 
called on to do the building. Somewhat like a more capable toolset. 
Although it would be a nice step if someone wrote a BBv2 toolset that 
just called on Scons. As that would be a quick way to start playing with 
Scons.
