without looking into the code, creating tikz->png convertor wont help?

Just to close this thread:
Defining an additional tikz->png converter does indeed solve the
problem. Another possible solution is to extend the convertDefault.py
script to recognize "TikZ:" as input format. For convenience reasons,
this is the route I have been taking.
If others would like to try this: Here are the step-by-step
instructions:
-- Under [File Handling --> File formats] add a new file format "TikZ"
as Vector graphics format, Short Name: "Tikz", Extension: "tikz",
and Editor: "vim".
-- Under [File Handling --> Converters] add a Converter Definition
"TikZ --> PDF (ps2pdf)" with Converter: "pdflatex -
interaction=nonstopmode $$i"
-- Replace the convertDefault.py script by the attached version.
Disclaimer: This are my very first lines of Python code!
Note: According to the docs, it should be enough to put the customized
version of convertDefault.py into $LYXUSER/scripts (~/Library/
Application Support/Lyx-1.x on the Mac). However, on my system (Mac OS
X, LyX 1.6.3) it seems to remain unrecognized in this position, so I
ended up with replacing the default version.
