Martin,

A few years ago my team implemented a custom solution for a client.  One on my team wrote a fairly simple java program and leveraged the Jazz/RTC api to create/update work items that originated in BMC Remedy.  We used BMC's api to access their Remedy instance from a workstation that ran our java application.  On the workstation we used windows scheduler to run the app, poll Remedy and then create/update the RTC work items.

It was a simple app that used very straight forward configuration files to define parameters.  It was also uni-directional in its initial version, only pulled from Remedy to RTC.

It took our developer a few weeks to rapid prototype, develop, test and deploy it for production use.  That being said, it definitely needed additional work to make it bi-directional and add better support for multiple repositories for source and target data, along with other nice to have features.

I have not heard of the symphony solution before.  In other engagements we have used Tasktop Sync and there is another IBM Rational business parent that has a similar synchronizer solution.  Tasktop is the only one that I am aware of that already has the BMC Remedy integration out of the box though.
