Basically I was planning on using the session as a clipboard for 
cut/copy/paste functionality of objects. Since it's a clipboard, a house 
cleaning of the session cookie isn't a big deal. Since it's for the 
admin interface of the plugin, I'm not that worried about cookies being 
disabled either. 1) Sessions can be supported without cookies (although 
how well that would work with WP would have to be tried), 2) the 
functionality lost is minimal. I wrote  a test plugin that stored values 
in the session and it appeared to work, however, there were posts on the 
support forum indicating that it could be a problem. I thought I'd check 
here.
