I encounter the same restriction. My use case is that I'm building an application composed by a few modules (each modules comes as a portlet package in a war). I use some page spaces in order to compose different views of my application (base on the role or the application context (summary page, detail page)). I can pass from one page to another but I need to instruct the target page (in fact the target portlets) for some params. So I build a sort of session Handler (DB storage) on top of synchronized by the sessionID. I don't like that to much (should not work on distributed applications), but I don't know how to do that differently. I regret the lake of a Portal Scope variable.
