I've just uploaded my first SparkleShare for Fedora (15) v0.4.0. SparkleShare is a collaboration and sharing tool.

I'm not used to SparkleShare so I'm not sure if all dependencies are well tuned. I've activated the support of libnotify and smartirc4net. The first is working but I don't really know how it uses it and if it's really working. Integration with Nautilus is available too.

The package quality is a bit under Fedora requirements but it's, but the application seems to me mature enough to add it to Fedora. I encourage you to contribute it. In the middle, please report here any defect you detect.

It's available in my repo. You can set up paquetes-rpm repository in yum. Enjoy.
