Yes, and it works out great, so far. We installed and imported the first 
hundred or so instances in short time now and we are happy! Off to the 
next batch of love-hungry TYPO3 sites :-)

The tricky part is that we of course need the remote site 
domain/hostname and the remotely generated pubkey, so we need to 
transfer that info from the remote system to the local caretaker master. 
Therefore, this first mass-import was done outside of TYPO3 for now 
using a little script that reads a CSV file (including hostname, pubkey, 
some meta data), mocks up the missing stuff (tests, instance group == 
"Newly imported", etc.) and imports it in a rush.

Hm, we'll think about that here, as well, since we'd like to have *all* 
monitoring data nicely integrated, with some more "green bar feeling" - 
with caretaker collecting the TYPO3-specific data, nagios doing the 
low-level stuff and alerting and a custom dashboard for presenting all 
that in its full sexyness.

My first thought however was "sys_registry" or some other generic 
storage as close as possible to "key=value".

Having about 100 instances in the system just made me realize there are 
some tweaks that need to be done. I already have some patches against 
latest trunk ("maxitems" => 10000, sorting/autosizing/greater height for 
instance and test selectors, etc.). I'll send them to you as udiffs in a 
couple of days.

Cheers
Chris
