Hi,

for each user I need to create and call
a dynamically named _GLOBAL_ variable (or Constant)
labeled with the user name.
To make it clear what I mean:

# begin "Ruby Pseudocode"
   user_name = "tom"
   $#{user_name}_dyn_var = "/path/to/nirvana"
# end "Ruby Pseudocode"

Is there a way to do that?
How would I call that new variable '$#{user_name}_dyn_var' ?
I tried "Module::const_set":

# begin Ruby
   constant_name = "#{user_name.upcase}_VAR"
   constant = self::class::const_set(constant_name, "/path/to/nirvana")
# end Ruby

but couldn't find a way to call "#{user_name.upcase}_VAR".

you may ask why I either need a global var or a Constant:
I am using the "live_tree" plugin 
from http://www.epiphyte.ca/code/live_tree.html
to create a file system browser.
As far as I can tell,
the plugin requires either a global var or a Constant
to initialize the file system model.

If someone has tried this plugin before
and found another solution, let me know.

Thanks for your input,
Tom.
