Kind of, only I'd like to be able to set timeouts less than 120 minutes.

from:
http://developer.apple.com/documentation/mac/NetworkingOT/NetworkingWOT-390.html#HEADING390-0

kp_timeout       Set the requested timeout value, in minutes. Specify a value of       T_UNSPEC to use the default
value.You may specify any positive       value for this field of 120 minutes or greater. The timeout       value is not
anabsolute requirement; if you specify a value       less than 120 minutes, TCP will renegotiate a timeout of 120
minutes.
