Well, that depends ...

Sounds like an echo ...

If it's something to be done once, or a few times, then yes, tools 
already available are great.

But what if performance is an issue, or the tools don't do 100% exactly 
what you want?

We're running services that get beat on all day long.  Sometimes very 
heavily. Performance is a critical issue.  I'm thinking that if I 
cobbled something together from off the shelf tools, I may not have the 
performance to do the job.
