There are some similarities but Fossil still has a push/pull/commit flow, although it does provide syncing features to automatically pull commits. Also, I don't think it has great support for large files.
Ultimately, the priorities of Fossil are going to be different than Jamsync, since Jamsync is not decentralized. Being centralized means that we'll be able to do some different things, like live file editing, but with some downsides related to replication and distribution.
