Win XP, multiple simultaneous Internet connections?

Using Windows XP SP3. I have two Internet connections, DSL and
through a wireless Hotspot.

In Network Connections, Bridge Connections seems to put both
connections into one. But the throughput seems to be no greater
than the faster connection. Should Bridge Connections make both
Internet connections work simultaneously? Is additional setup
required?

If that is not supposed to work... Is there some other way to use
both connections simultaneously in Windows XP? Can one program use
one connection and another program use the other connection?

Just trying to be clear... Can you use two connections at the same
time in Windows XP? If so, how?

Thanks.

BTW... I am asking in other groups and doing a little research.

ForceBindIP -i {GUID, from Regedit} "C:\Program Files\program folder\program name.exe"

Preliminarily, that seems to do the trick.
