I will answer the hardware part only:

it has to be USB, since a modern PC (desktop or laptop) has 2, 4, 6 or more USB ports
and often 0 serial ports.
furthermore, if I need several hardware locks, its much easier to add USB ports (using
a USB hub), than it is to add serial ports.
and lastly you can easily have USB ports at a distance, such as the USB ports found on
many desktop monitors.
The performance issue AFAIK is irrelevant since an app will typically check the hardware
lock only once (at startup), or a couple of times (when saving something),
certainly not all the time.

BTW there are companies such as WIBU[^] that sell
USB hardware locks; they are organized in such a way
that they can hold a number of keys plus a couple KB of app data; so a new software
can be linked to either an existing key or a new, empty key, and that is how it should be.

And of course, companies that offer hardware keys also have the necessary software
to support them, including an API to integrate it in the app itself.

To sum it up, whatever your software product is going to be, if it comes with a
serial port hardware lock I wont buy it. If it works with a USB key, it better be
from a trusted hardware source and able to combine with other protected packages...
So I dont see the point in reinventing stuff that exists and performs well.
