Hi,

After having used S+ in commercial setting and then R
in non-commerical (but still supporting my commercial
interests), I would like to give back, if possible.

Where I can contribute:
1.  SCAN / PREVENT Stability and Threat analysis (big
open source presence supported by coverity)
2.  Intel Threaded Building Blocks library support to
leverage multicore CPUs (plan now for 8-way)
3.  VTune analysis/cache optimization for
identification of loop unrolls, etc.

All this would be on linux (Fed8 at present), except I
do have an Intel compiler on Win if it was needed,
would need to find fortran compiler, make lots of
adjustments, I suspect.
 
I've already started on #3 and would only take on #1
if someone in the R project blessed, because David
Miller at coverity likes to support the broader
projects over lone-cowboy stuff.

P.S. What an easy build, as far as open src goes, your
build person deserves credit.  I'm currently setting
up to compare gcc to intel compiler on the R base and
rerunning the timing benchmarks.

  Thanks.
