[kepler-users] transfering proxy information between actors.

[Jianwu Wang]

Hi ufuk,

    That's great. Thanks for your work and info.

   Kindly reminder: most Kepler developers subscribed both kepler-user 
and kepler-dev mailing lists. You just need to send emails to one of them.

Best wishes

Sincerely yours
