Well here it is - an alpha version of BlogSmart for you to try. It's not great but will allow you to logon to your site, view the 5 latest posts and create new posts. More stuff to follow!
You'll need a config file called bs.cfg located in StorageProgram FilesBlogSmart in the following format:
entry description url to site with xmlrpc username password
So for example it might be:
0gravity.co.uk http://www.0gravity.co.uk/wordpress/xmlrpc.php username password
You can download it here
