I have done some experiments. You will need:

- sticky sessions (i.e. all sessions go to the same server)
- Well replicated content
- Well replicated psml resources (either files or use DBPSML)
- A common or replicated DB to handle USER information (and possibly PSML).

The issue of replicating PSML (or having DBPSML) arises from the ability 
of a session to write a customized PSML, logout, and then get a new 
session in a different server.

External resources (such as the ones that the URL cache handles) will be 
fetched repeatedly unless you fix it either by having a external proxy 
or you rewrite the URL cache as a remote one.

Using a proxy will not work completely, as most or the external feeds 
are marked by their origin servers as "non-cacheable".

Will jetspeed work on a multi server farm behind a load balancer ?
Has anyone tried it, if it should work?
