Web Facing and the Outside World

I am trying to get some stuff up and running on the web. I have a project 
(Web Facing Project) that I created and it runs fine, of course I am 
running it internally.
I read some earlier posts from way back that said some things about web 
facing running fine in-house, but performance among other things were an 
issue when used over the internet.

Anyone have any opinion?

I already have some alternatives that I like, but first web facing needs 
to fail before I approach these other solutions.
Web Facing plus is that everyone in my group knows RPG and could work on 
the actuall programs, I would have to deal with updating when necessary, 
but they could all work on the applications. Another is the fact that is 
not one more thing we have to purchase, we already have what we need.

Just looking for some other opinions and to see what other folks are 
doing.

Thanks!
