Hi It would be nice to have on something like this; http://cubloc.com/product/05_02.php
(with linux of course) or; http://www.linuxdevices.com/news/NS2304885763.html So the whole thing would hanng together like this; http://controlafzar.com/products_en/controller_page.htm Regards Roland Jollivet 2008/11/22 Jack Coats <[EMAIL PROTECTED]> > For a different approach...
