RIKEN-BNL-Columbia QCD Project is prepared to start lattice numerical
calculations relevant for proton spin, using

	- its TFLOPS QCDSP parallel super computer,
	- and 5D Domain Wall Fermions.

Roughly speaking the former will bring us closer to the continuum, to
somewhere between 2- and 4-GeV lattice cutoff, and the latter enable us
to study with the right number of quark flavors with proper chiral symmetry.

Yet the resource is still limited in the sense that we will not be able
to calculate all of the proton structure functions.  Instead we will
have to concentrate on a few most important and/or interesting ones. 
The likely candidates are DIS F's, g's and h's with known factorization.

We hope to extend our study to those more directly related to RHIC Spin
experiments, but that would require further clarification of
factorization and gauge invariance issues.
