Websphere Support

We are currently evaluating some ECM products and Nuxeo is one of them. As far 
as I understand Nuxeo only support JBossAP and soon Glassfish.

As my company is using Websphere as the application server, if we choose Nuxeo 
we would like to know if it is possible to deploy Nuxeo on Websphere? Have you 
ever tried or not? Which version? 

Do you have plan to support Websphere (6.1 I guess) or not?

Thanks
