thanks. sorry for the delay, i'm just getting my head back into things after
a nice long break. it will be awesome to work together and improve the
framework. after all any workflow engine slowly becomes a meta-language!
also, ipython, will have some nice features that should reduce the nipype
code and make for a cleaner implementation. also chris at enthought is
converting traits to pure python and that should clean up the engine code as
well. we currently have some work-arounds for a couple of dynamic traits
do send me some more details of what you want to do. (based on what you have
below, you should find our base classes rather appropriate).
