OK, I think I understand.

So, at the top of my browser right now, instead of it saying "Hosting Discussion - Website Development & Design - Mozilla Firefox", it might say something like "Hosting Discussion - Website Development & Design - Is this possible? (automated browser title) - Mozilla Firefox".

I can see decent usage for something like this that would be based on random or user variables.

And don't worry so much about getting flagged by Google. If anything like that would throw a flag up, they manually check it first without penalty. If it is a legitimate reason and not an obvious method to manipulate SEO, then you'll be fine.
