It can be done.

Using the MathLink API would be an appropriate use here.  Basically, your
C program is working as an alternative front end to the Mathematica
kernel. The MathLink Developer's kit that appears on the professional
version of Mathematica contains some sample C programs that demonstrate
this kind of connection.

Depends on the type of license you have.  In general, as long as the
kernel is running in a manner in line with your license, it matters not
where your C program is running.  The only hurdle you have to overcome is
to provide a mechanism for remotely invoking the kernel (e.g. RSH
protocol).
