I have clustered Jetspeed 1.6-dev and 1.5 in several installations.

Jetspeed-2 is not quite cluster ready, but I think it was designed much 
better than Jetspeed-1 for clustering. Many of the components already 
persist their state in a database, so therer is not a lot of need for 
tweaking the implementations like we had to do in 1.6.

The plan is to work on clustering for the final release.

Current problems I see with Jetspeed-2 and clustering:

* PSML stored on the file system
* lots of use of the session
* cache synchronization on a number of components
