A long, long time ago (2002 feels like a long time ago, anyway), I wrote a little tray app called Screen Saver Toggle. It worked well enough, but time revealed some issues which, with the passage of a great deal more time, I got around to addressing. And here 'tis.

It does what you would expect from the name, blocks/unblocks the screensaver; it was originally unique in that it was the only utility like this (that I knew of) that did the job simply and quickly, one click and you were done. Nowadays there are several similiar apps that are just as quick and easy. Nevertheless, I'm still fond of the ol' app, so I updated it.

It has retained the 'simple and quick' characteristics, and done them one better: mouse-o-phobic users can call it from scripts now to toggle it or force the screensaver, or whatever, which means it can be tied to a hotkey, or made part of a command file sequence of events.

Thanks for all the advice, guys. I didn't see wraith and mouser's posts before I talked to the guy, but it worked out anyway.  

I made it clear exactly what I was willing to do (i.e. absolutely nothing beyond the simple set-up originally described), and gave the guy the number of a local full-time web guy when he starting talking about "getting lots of hits."

SEO wasn't in the original description, so it gave me the excuse to pass it on this way (didn't want the job in the first place, was obligated to meet with the guy for family-politics reasons). Er, you may wonder why I didn't just ask the full time guy for a price in the first place; fact is, it just felt kind of rude. You know, "Excuse me, sir, what price should I charge to undercut you in obtaining some local business?" Wouldn't matter how I phrased it, the guy would know the intent. Or at least that's what I always imagine in situations like that.

Thanks again; the info in this thread now gives me a great starting point to work from if I should get cornered again!
