I have a relatively low end D-Link Websmart switch that supports LACP
configured using IEEE 802.3ad Dynamic link aggregation on my server.  It
was a relatively easy setup and while I agree that it's not quite what high
end solutions may be capable of, it does balance multiple connections quite
well.

802.3ad, as I understand it, purely provides redundancy, and allows
multiple conversations to be spread across the links.  So, for example, if
I have 4 frontends playing video and two HDHR's recording, 3 connections
would go across one link and 3 across the other (in theory).  If I try to
download a file, to my workstation while all of that is happening, I would
only see the remaining available bandwidth of one of the links as
connections cannot be split across the two.

In other words, my solution is ideal for mythtv where traffic consists of
several concurrent connections... but wouldn't do much if your goal is have
massive bandwidth on a single connection.  At very least it is an
improvement over dedicating Gigabit NIC's to a HDHR... as there is a lot of
available bandwidth not being utilized, that could be used by a playback
stream or two.
