Well, that was fun - reading the installation notes for Hubzilla, and they keep going on about how you can install it on just about any server that can run WordPress - it's just a pity that there are 2 PHP extensions that are essential for Hubzilla, none of which I can modify through php.ini on my shared hosting.
Just put in a support ticket, but it is Friday night, they are unlikely to do anything non-systems-critical until Monday, by which time I will have forgotten about then whole thing!
