I applaud your attempt to make a transition easier. Having mostly the same programs available in a new OS is comforting to most people. When I migrated Mom from Windows to Linux, she was pleased to see the same programs used that I'd taught her on Windows during the prior 5 years.

1) Java is a security risk when run inside a browser
2) Java applications tend to load slow, used lots of RAM and have a dated look and feel.
The folks building Ubuntu probably selected the best alternative for VNC clients, IMHO. Your people can learn to use it as well, I'm certain. If needed, a side-by-side how-to guide to show them where X in RealVNC goes into field A under the build-in VNC client can't be too hard to create. After all, there are only about 10 settings for VNC clients.
If you really want to blow them away, you might consider using NX instead of VNC. The performance is 2-3x more efficient, IMHO. It is snappy compared to any VNC that I've used. https://help.ubuntu.com/community/FreeNX has a setup guide. Of course, you might not control the servers or there might be so many that setting up NX on each isn't practical. Only you can decide.
Google found this: http://www.plugintolinux.ca/smf/index.php?topic=815.0 which claims that xvnc4viewer is realvnc. I dunno. To install:
$ sudo apt-get install xvnc4viewer
Seems to be true:
VNC Viewer Free Edition 4.1.1 for X - built Feb 5 2012 20:02:23
