[BioC] Getting dChip SNP intensity in BioC?

There's some good info in there, thanks!  This isn't quite what I'm after
right now though, I'm trying to go in the other direction - exporting data
from a BioC session into a file to read into dChip & genepattern (their
formats are similar for SNP data, information on GP's .SNP file format
is available
here: http://www.broad.mit.edu/cancer/software/genepattern/tutorial/gp_fileformats_text.html#snp).


I know how to generate the SnpCallSet object to get the call information,
but both of these programs also want the signal intensity data to go along
w/ that, which is what I don't know how to get at within BioC.
