I believe what you're looking for is explained in these documents:
http://www.rubycentral.com/book/web.html
http://nubyonrails.com/articles/2006/02/01/rjs-and-content-type-header

The first method is the easy one and will do exactly what you want - at 
least, I think so since I have a similar requirement. I need to be able 
to run Ruby on one server but be able to call a script on the first 
server from a different server's HTML content. I've done something 
similar with Python and PHP and it worked fine. So I believe the first 
link examples should work as well though I still haven't tried it. The 
second document about RJS appears to provide a more complicated way to 
do the same thing but again I'm not absolutely certain since I haven't 
tried it out :p

Incidentally, if you set up Ruby to output HTML in the above fashion, 
the example call you used:
> <script src="path/to/hello.rb" type="text/ruby"></script>
would have to be done as follows:
<script src="path/to/hello.rb"></script>

Hope this helps, or at least puts you on the right track :)
