[BioC] 4-color microarrays

We're currently beginning to use microarrays with 4 colors, and I was 
wondering whether anyone out there had any experience analyzing those 
using Bioconductor?

I've previously used limma for normal microarray analysis and also for 
arrays with just 1 dye. I've been quite happy with that, but it appears 
that if I want to continue with that I have to e.g. split the data from 
each array into two 'pseudo-arrays', which isn't exactly optimal. I 
won't be doing expression analysis, but I'll need functions for 
normalizing the data etc. Has anyone tried something similar?

Thanks in advance
