Hi congratulate for the turnkey appliances,
it's exact what I'm looking for, ubuntu based and ready for go in a virtualbox environment.
It would be fine if you publish also two new appliances to your growing pool (45+?)
I'm interested in a memcached only appliance (small overhead on the base system for getting as much memory for the cache system). It would be even finer if the memcached server state (memory usage, etc.) can be controlled remotly in the web-frontend ;)
Besides this I also look for a lighttpd web-server appliance that gives me a very fast web-server as an alternative to the apache based servers.
