Why specifically *without writing it to harddisk*? Webservers are 
stateless, so on each request everything needs to be built from scratch. 
If there is a cookie that indicates that the FE user is logged in, the 
FE user data is fetched from the database.
Therefore you need to store it somewhere to be able to retrieve it later.

You can use the proper API to store it:

$GLOBALS['TSFE']->fe_user->setKey('user', 'your_key', $value);
$GLOBALS['TSFE']->fe_user->storeSessionData();

and retrieve it with:

$value = $GLOBALS['TSFE']->fe_user->getKey('user', 'your_key');

That would imply that you extend the FE users table with a new property.

You could extend the FE users table, but if you want to set it on page 
'A' and read it on page 'B' then the value needs to be stored ("writing 
it on harddisk").
