MySQL Workbench have been approved for official Fedora Repository.
So, fedora 13 & 14 users can install it with the usual tool
yum install mysql-workbench
(well, only in "updates-testing" for now, but it will be pushed in a few
days in the stable "updates", at least before fedora-14 release)
Of course, it stay available in my backport repository for older fedora
version (11 and 12)
PS. it probably worth an update of http://wb.mysql.com/?page_id=195
