The real question is -- does boost even offer a smart pointer type that
replicates
ref_ptr, or is all this a pointless exercise?
I've stepped through ref_ptr code before and it does seem similar to
intrusive and perhaps shared as well. I have also discovered a few matrix
classes that are public one of which is optimized SSE and SSE2, where some
of the benchmark code pointed out a standard to work with them among several
offered (including Microsoft's).
The most attractive thing about standards like std::, boost, and tr1, is
that they are tested extensively by a wider c++ community and so they must
be pretty darn robust and more versatile, but more important if you are like
me and code for more platforms other than osg, you'll find it extremely
useful to be able to transfer knowledge of one standard and apply it to
multiple projects with completely different environments.

I like boost myself, and have used parts of it in different projects.
But, I want to
clarify the sense of "installed" here.
I'd differentiate the multiple meanings of "installed" into
headers-installed and
libraries-installed. To use any part of boost in your code, you (the
person compiling the
boost-using project) must have the boost development kit with headers
installed. This is
one component that OSG doesn't currently require. It's pretty
version-safe -- generally if
you require boost x.y.z, any version > than that should be fine.
Judd is right in that most of boost does its magic at compile-time and
doesn't need
binary libraries at link-time.
However, it seems it is still possible to get in trouble when you mix
binaries compiled
by different people who used different versions of boost -- whether they
were using
compile-time or link-time portions of boost.
Because OSG incorporates other third-party libraries (such as Collada)
that incorporate
boost and are difficult for individual OSG developers or the project
maintainers to
recompile every time something changes, we've run afoul of this problem
and are gun-shy.
The real question is -- does boost even offer a smart pointer type that
replicates
ref_ptr, or is all this a pointless exercise?
