BugZilla interop support
BugZilla supports an XML-RPC api. For those of us who can't immediately migrate away from BZ, but want to get started using Redmine. Some sort of interop Rails/Redmine plugin would be AMAZING.
Maybe it could/would require direct field mapping (and thus some custom fields be added to the "Issues" area in said Redmine instance) and do a sync via a rake task (which could then be scripted via cron), manual sync via the Redmine web admin interface or upon certain events being fired. Like when a new issue is created in Redmine, allow for mapping to an existing BugZilla bug or creation of a new BugZilla bug. I know I'm probably dreaming here towards the end, but this would really help users who currently heavily rely on BugZilla right?
