Second - will this mess me up when Google comes to index my page? Right now the google bot comes like clock work every month. I do not want to make page unreadable for the spiders.
Thank You - Shawn :)

[edit reason] no urls thanks [/edit]
Personally I cannot see why anyone would want to encrypt their HTML source! Sure, being a newbie you may think your HTML is out of this world and people are going to come from miles around to steal your cleverness. Truth be told an experieced coder can pretty much just look at your site and reproduce it at will.
It is not that I am a NEWBIE nor do I think my code is "spectacular". There are times when I create demo sites for a client I am trying to secure that I want to hide the code. Why? because there are certain competitors here that I would rather not educate. If you can look at my website and reproduce it without "view source" then kudos - I do not care. But I wont educate my less than savy competitors if I can help it.
So with that aside - I am still looking for an answer - no full of themselves responses.
I understand your point, and I sure TheWebographer didn't meant it in a wrong way.
About using your php script.
1) Just upload the php script that you are downloading from the site.
2) Place the script in root directory. (you can place it anywhere though)
3) Place <?php include('csource.php')?> on every page that you want to encrypt.
However you might want to keep few things in mind.
1) Search Engine spiders (including google) will not be able to read the code of encrypted pages. So it is a good thing that this script does not encrypt all the pages, but only those pages that has <?php include('csource.php')?> on the top of them.
2) You will not be able to encrypt .html or .htm pages (unless you are phrasing them as php). So you might also wanna keep this this in mind.
3) Your best bet would be. Create clients demo only under one sub like www.domain.com/demo/client1, www.domain.com/demo/client2.... etc and for all the site make a template with <?php include('csource.php')?> within the header. So you will not have to remember to put <?php include('csource.php')?> in every page.
4) Make sure that you put the appropriate path in <?php include('csource.php')?>, cuz, if you want to encrypt pages anywhere but in the root directory, <?php include('csource.php')?> will not work - you might wanna use <?php include('../csource.php')?>
Hope this helps.

Sticking to the laptop is a good idea also.
