yup, that's why i'm asking. :)

if you'd explain what consolehelper does exactly ... :}

well, two protocols are one too much, as far as "standard" is concerned,
no? ;)
what kdm currently does is clearly insufficient for the features i'm
planning, so i have to come up with something better anyway. i'm not sure
whether i will just use/extend the gdm socket protocol; i'll have to
investigate that (but you can expect some significant changes, if :).

i'll try to write some half-assed spec for the dm-related part of all
this, but if i'll be as fast as last time ... :}
