Hi Andriy
I've got two comments to Your problem:
1. With ALTQ You can control only _OUTGOING_ traffic but not incoming.
So the only way to contol incoming traffic on 1) is shaping of outgoing
traffic on other interfaces.
2. You have to make drivers for Cronyx Tau compatible with ALTQ in order
to achive Your goal. If You'll do so - please let me know 8)
