I've been in this situation before too, and it would be very handy to have the GL_RENDERER and other identifying strings stored in OSG for the user code to query. Since many people don't know you have to have the context valid, and others don't know where/when OS has a valid context bound, it would be useful.
Potentially, this information could be per-window-specific, couldn't it? Multiple heterogenous display cards on one machine could return different results for different contexts.
