How fast is the IR port that's built into my laptop, for instance?

Correct. AFAIK 196 kBit/sec is the maximum speed. On the
computer-side it is just a com-port and many boards have
dual-use com ports that can be used for IR and as regular
com ports (different voltage levels on both).
I think IR also has a syncronous layout, but that just means
that the pause between two frames (words) has a fixed
length, while in the commonly used asyncronous from it
is of arbitrary length. The delay between data transfer
units (Packets with header, body and trailer) is still
arbitrary.
