RTC repository synchronization tool
Accepted answer
Out of the box, the the only "client" of the RTC Item Connector system is ClearQuest. I know of customers that have used the RTC Item Connector system to support other clients, but it is a significant amount of work to do so. So in theory you should be able to create your own RTC client for the RTC Item Connector (and use it to synchronize RTC to RTC), but I don't know of anyone who has tried this.
One other answer
There is no tooling provided to do this.
One could be created, but it would be more than an Item Connector.. the Item connector is the outbound interface.(something changed here, tell the other side).
when I built my item connector, I also had to build a web service for my other side to call. that web service used the item client interface to push the changes into RTC
this was my design (salesforce service cloud on the other end, but same concepts)
the difficulty with RTC is that you will need the client apis to talk to the other end outbound.. and as the item connector runs as a subroutine of the server, you do not have access to the client apis.
