Check out the webbioc package in BioC-Devel. It does web-based analysis of Affymetrix data from CEL files to annotated HTML lists with hyperlinks to online databases. It also creates M vs. A, QQ-Normal, and multiple testing procedure selectivity plots. The image quality issue was solved by using the GhostScript bitmap() device to super-sample PNG images at 4X resolution and then scale them back down to nice antialiased images with Netpbm. I don't know if this will do what you want. (I'm looking for someone to add a cDNA chip input module.) Perhaps the code might be useful for ideas. (Mostly Perl calling R in batch mode.)
