Can I have ONLY one instance of the fckeditor code?

Can I have the fckeditor code in only one place on my domain and have several users access it?

Erm: OK... this sounds like a very dumb question!
I thought I'd ask anyway.

What I've done is to tweak the editor so that it can be called from different places and in each such call, there is a different place to put things like images.
Does that make sense?

Previously: I had a new copy of the code for every place where I need the editing done.

I wanted to know: would there be any problem in the load on the server or something?
Is it better to have several instances of the code in certain circumstances?
Will I be OK if 100's of users are accessing at the same time?
(Another question: if 100's of users are suing, what would the server load be like?)

Thanks.
