That is part of but not totally what we'd like to have. The problem are 
extension scripts on clients. An example:
One machine may be nameserver using the name xxxdns.uni-frankfurt.de, 
webserver using the alias xxxweb.uni-frankfurt.de and databaseserver 
using xxxdb.uni-frankfurt.de at the same time. Each of these aliases has 
local extension scripts running which send data to (so far) bb-display. 
In bb we hacked bbinc.sh to get $MACHINE set to the first alias and we 
could use bbaliasname to enable a second alias. bbexttab is created 
dynamically so extension scripts for these two aliases will work. There 
is no way I see so far (except of starting these scripts by crontab 
instead of bb-client) to enable more than these two aliases to work 
correctly with extension scripts.

kind regards
