[Bioc-sig-seq] read counts of multiple samples across all regions

Hi,
I have run RNA-seq on 4 human samples, and I'd like to look at the count
number from each sample at regions where any of the sample has some read
coverage (say, threshold of 5 reads). What is the best way to do this?
It is basically to examine the differentially expression regions across
the transcriptome, not just limited to known annotated regions. I having
been trying to use IRanges and related packages, but things start to get
hairy when come to cluster the reads, condense them (within certain bp
range), back-track the identities. I also looked at Cufflink, but it
does not seem to be for this purpose, isn't it? Any advice is highly
appreciated.
