I looked on their Sourceforge page, and it looks like they have lots of 
releases (2.2.8 latest)... So what's the problem? When can I expect a 
Redland release with 3store?

The reason I'm asking is that I'm investigating the possibilities of 
porting a JXTA/DAML+OIL framwork that I've done (in Java) to C (or maybe 
C++).

What is it that Redland lets me do that standalone 3store won't do?
