I do this by assigning an IP address (i.e., the same address) to the
interface I want to use and then replace the default route to go to the
correct interface. This works fine with static IP addresses and the
existing TCP connection survive the change. In other words, MAC
addresses need not be changed for this..

Which version of the driver did you use? If not 0.2.4, please try with
it. I fixed a bug in MAC address changing just couple of days ago..
However, this was mainly for Master mode. I have not verified whether it
changed anything for the client mode.
Please also send more detailed description of exactly which commands you
used in in which order to change the address, set the interface up, and
I just verified that changing the MAC address works fine in my setup
using v0.2.4 of Host AP driver and wpa_supplicant.
