At the end of the day, KSplice is a service that offers binary patches from
$old_kernel to $new_kernel. This means that it probably works by analysing the
old kernel build and the new kernel build, and then generating a patch that
specifically targets the said build.

Every distribution has their own build of the kernel, and as such, you can't
really use patches for one kernel on another, I reckon, in the same way that you
can't load kernel modules built for one kernel version on another, or kernel
modules built for one distro's kernel on another (unless you brought along the
entire kernel).

It is quite likely that the service for Ubuntu desktop could actually be used on
an Ubuntu server as well though, since both of them use the same kernel.

Apart from that, it is quite likely that you would need to pay them for the service.

In the case of KSplice, it probably doesn't matter much, since I do not think it
was an open source thing to begin with, or each distribution vendor could
generate their own KSplice patches, or even have them automatically generated on
the target machine.
