I wouldn't call that a "static" IP, it's still DHCP as far as the machine
getting the IP is concerned, it was still assigned by the DHCP server.
Static means the interface has a definite IP that will work without a DHCP
server. Setting up the DHCP server to always assign the same IP to a given
MAC still means that machine can't speak to the network without the DHCP
server running on the net.
I'm not sure what would happen if the IP you have assigned to a given MAC is
the only address available in the pool when a different MAC requests an
address. Would it refuse to give any address at all, or would it go ahead and
assign the one that the first MAC was supposed to get, and what would then
happen when the first machine comes up (assuming an address has been freed
up, would it then be assigned "incorrectly")?
Since I don't like mysteries, I assign any machine that's always on my net a
real static IP, using DHCP for transient machines like notebooks or guests. I
can then assign different firewall rules to addresses in the DHCP pool, so
guests are restricted in what they can access.

Not that I'm aware of, but you never know.
