yes indeed thats a good idea.

Perhaps we shall begin with pointing out whats maybe good in general on the one or other panel out there.

Lets start with ispman - the concept is really nice
which means (they use ldap for storage things )
and they've the same agent - master concept i'd like to have

second - syscp
the new 1.4 has a nice code-design (everything in modules with hooks available to place plugins in there)
