[OS X TeX] LaTeX macro question

I'm trying to write an environment that does the following things: (1) saves the verbatim text between the \begin and \end commands as a list of tokens, (2) computes a simple hash function on that token list to generate a value (so as to be able to detect when the content changes), and (3) uses \scantokens to re-process that list of tokens so as to typeset it "properly". 

Right now, I'm having problems with (1) and (3) — I just can't seem to figure out how to save the verbatim text and then process it with \scantokens.

I know the following lets me save verbatim text:


    \draw (0,0) -- (0,1) -- (1,1) -- cycle;

And now I can typeset that as many times as I want via \UseVerbatim{asdf}. 



Just reproduces the same output as \UseVerbatim{asdf}



produces an error.

Any suggestions would be most appreciated!
