Hi Paulo:

I hadn't heard of gdm dropping support for gdmdynamic.  That would not 
be good.  Any more information on that?

I have two wish items for gdm in re mdm: autologin on arbitrary heads 
and the ability to specify custom themes, per head ideally.  It would be 
good, for example, to provide a login with the terminal name and an icon.

I started to look at the code, and it doesn't look too difficult, but my 
real job interfered.... (I have a large project that is 6 months late 
and still falling behind.... So my focus is on that, and probably will 
be through the new year.  :-( )
