Another option could be to have a hidden iframe and navigate to a page (via
javascript) that returns the session variable value (for instance, something
getSessionValue.aspx?var=varName).

The getSessionValue.aspx only needs to do the something like
Response.Write(Session(Request.QueryString["var"]))

Then, you can access via Javascript to inner value of that div

This option gives you session information at the moment, but you have to
deal with syncronization issues and javascript client programing.

Leon
