--000e0cd112dccfb7ef047ec44702 Content-Type: text/plain; charset=ISO-8859-1 Hi, not completely sure I understand what you are trying to do, but Robert's post got me interested, and I wanted to try it out. This is what I came up with: http://gist.github.com/294520 ( mirrored at http://pastie.org/private/1gtz2apwaxac2rcgl3xsw because github is having issues http://twitter.com/github/status/8627608544 ) Hopefully it's helpful, if not, maybe flesh out the example a bit more of what you want to do, and what you want other people to be able to do. --000e0cd112dccfb7ef047ec44702--
