I also would shy away from web services, axis, or XML conversions in general unless you need them for some other reason.
I know of a company called PeerDirect which has replication technology that works well for the type of scenario that you're talking about. I'm not sure if they're ideal for your particular situation, but they have a very clever set of technology to deal with the replication/synchronization problem. It's also vendor agnostic, and can be used across different platforms. You can find more info at http://www.peerdirect.com/ . Also, just to make be honest, I work for PeerDirect's parent company, Progress Software. I don't work with them, though, so I can't really be more helpful. If you're interested in more details, though, you can drop me a line and I can get you talking to the right people.
