Will there be multiplayer through Impulse for any of these games? I already own them, but have been unable get the multiplayer to work (at least for icewind dale, the only one we've tried) since upgrading to windows 7.

I doubt that any of the games will be updated with multiplayer through Impulse.
Baldur's Gate and Icewind Dale were originally released with TCP/IP networking, so you should still be able to easily start a multiplayer campaign. Finding a campaign to join may be more difficult - I don't remember either of these games having an in-game game browser (a screen that lists available multiplayer games).
