Ask HN: Does opstow sound good for a monitoring SaaS ?

I'm currently setting up a monitoring service for startups including mine (think graphite+prometheus long term storage)

I was looking for a name for this service and asked for ideas. The intial proposal were : perfmonkey, hackstream and streamstow.

From this first batch I kept streamtow. Now I have a new one and want to know what you guys are thinking about it.

1) opstow : which I like a lot 2) streamstow : the old one

So which one do you prefer ?
