I am able to say! I have a couple of web / craft apps that I want to put online, but since they serve content directly, rather than through webserver software, I'd need a dedicated server for them. That could go in a datacentre, but I'd have to have dedicated hardware, or rewrite! Co-location prices already make SDSL look economically attractive. One of the applications requires some dirty (not absolutely, but dirty for a clean-room) mechanical hardware to be attached to the server with some better-than ADSL bandwidth requirements, so even if I could find some co-location that offered that kind of service, I expect it would be expensive - it needs at least hourly physical attention, and it is dusty. As it is, a few minutes with a hoover and mop at home, and my wife is happy that it's not dirty enough to make spending a fortune on a factory necessary.
