Vista - Bandwidth Throttling

It would be nice if there was an option to limit the bandwidth used by the
application. Whenever I add sizable files to a share, or add a share to a
new computer, my home internet connection gets saturated on the upload side,
killing my roommates' Xbox Live games.

A separate limit values for LAN and internet would still allow for full
speed transfers between local machines while not overloading the broadband
connection.

Thanks,
