peak calling for virus chipseq

[honey]

I am interested in identifying viral particles in a chipseq experiment ran on Hi-seq. I used viral antibody using to perform IP. Is there any special tool for calling peaks in such small genome as binding sites may be very closely spaced. I guess I cannot use MACS or SICER.
Can anyone working on viral Chipseq share their expertise.
Thanks

I don't work on viral ChIP-seq but by chance I saw this package today:

http://pypi.python.org/pypi/pique/0.1.1

It might be interesting to look at since it is made for high coverage / small genomes.
