Rails spinoffs - Feb 2008 - Loading Prototype after Prototype was loaded. Unkown enviroment

Hi all

I''am about to write a widget that uses Prototype. Something like a
facebook widget, but for just any website, blog, whatever.. So i do
not know what javascript is already in place on the target site that
includes that widget.

Now i wonder what happens if the site - where i remotely include
prototype.js on load - already has prototype loaded.

Wouldn''t that break the sites own javascript functions / overlap?

Is there any way to "sandbox" the library so it is safe to include?

Of course i could test if prototype is already loaded, but what if
it''s an older version.. i probably would have to load my remote
version anyway, but that could still lead to conflicts on shared
functions, no?

Any hints are highly appreciated.

Best,
Kjell
