Special Interface Aggregation With TRUNK?

Hi!
I'm new to OpenBSD, and want to setup a firewall router with it in the near
future. I am planning a special setup with four NICs and two different ADSL
lines:
rl0: ADSL 2048/512
rl1: ADSL 4096/768
re0: DMZ
re1: LAN
Both ADSL lines should be aggregated, to combine the down/upload-bandwidths.
As far as I could read by now, TRUNK should be, what I'm looking for.
The problem is the following:
There will be one computer in the DMZ, which should be forced to only use the
ADSL 4096/768 line on rl1 for both down- & uploads, all other machines in the
DMZ or the LAN should access the virtual trunk interface and benefit from the
combined bandwiths.
So my main question is, can the physical interface rl1 be accessed directly,
although it is part of a virtual trunk interface?
In OpenBSD 3.8 there is only the round-robin algorithm suitable for trunk in
such an application, which seem so be pretty simple. Will it be able to
handle the two ADSL lines with different bandwidths flawlessly even under
high load, and how will it react concerning the interface rl1 being accessed
directly by the one computer in the DMZ directly?
