[BioC] Filter over group averages

Is there a way to easily filter genes on the average signal over groups
(according to phenoData?). Let's say that in phenoData of my eset object
I have 'Time' and 'Status' variables, which have 3 values each. I have 3
arrays for each of the (9) conditions.
What I want is to keep genes with an average value of at least 100 in at
least one of the resulting 9 conditions. The genefilter package
seemingly only include functions to filter genes ignoring groups - is
there an easy way to do the same taking into account groups?
