exec ipconfig /all
capture the output.
Parse for "IP Address" and "Subnet Mask".
Your broadcast address will be your IP address bitwise-and'ed with your
subnet mask, or bitwise-or'ed with the compliment of your subnet mask,
depending on the kind of broadcast you're interested in doing.

Remember to handle the case where you don't have TCP installed, you have
more than one interface, etc., if appropriate.

(I'm assuming that that's enough of a hint to anyone who actually has a
use for knowing their broadcast address. ;-)

Don't take home left-over tripe.
   It'll just digest itself before
     you get around to eating it.
