[BioC] cross-species affy analysis

hello list,

I am approaching a meta-analysis task where I have to compare Affy data 
from human, mouse and rat chipsets.

I have seen some interesting things in Gregoryev et al. GenomeBiology 
2004. There, the authors have used external tools (RESOURCERER and EGO) to 
define the ortholog gene sets between several pairs of Affy GeneChips.

I was wondering if since then, any internal BioConductor tool has been 
developed (or it is in the plans of BioC developers for the future).

do you have any operative suggestion different than the one used by 
Gregoryev et al?

Thank you very much in advance for your kind help.
