I've started using TikZ for a paper I'm writing and am worrying that a journal might not accept the paper with inline TikZ. I had to update my PGF installation for all the examples to work and I'm not even sure that my collaborator will have an updated version...

So here are the questions.

-Do people know if journals (math and physics) accept inline TikZ? 

-Is there a nice way to create a pdf figure from a tikzpicture ? Perhaps I could have a latex file for each figure and only one \begin{tikpicture} \end{tikzpicture} pair and somehow compile the result to get a pdf or eps containing just the figure (and not a whole page with a figure in it...)

Cheers,

Yossi.
