Most online hosting packages are set up using what's called a 'shared server' experience. Basically this is multiple hosting accounts on one system, all sharing resources and generally without any full root privileges. Things like SSL certs, databases, etc are all 'shared' and some services/functions tend to be disabled (Tomcat for example).
I just wanted to know if there were any strange configurations in OwnCloud that would mean it could not be set up and run from a shared server where such things are limited/restricted.
It doesn't matter anyway as I can confirm that it DOES work fine (so far) on shared servers. I successfully went ahead and installed/configured OwnCloud on one of my own hosting packages as a test.
Only limitation for me now is that my provider doesn't allow hosting packages to be used as 'backup' or file storage facilities - everything must be publicly viewable
