Erik, Been gone for a few days, not sure if you got an answer to this or not.
I don't know why the asymetric performance but I can tell you that much of the problem is Shaw! I've got 5 IPSec LRP gateways going and have connections with Shaw, Telus and a wireless ISP. When Shaw enters the equation, the transfers drop through the floor as you've seen. Using the wireless and Telus ADSL, I see better than 300 kbps through the tunnel. Add one Shaw gateway and I'm lucky to get 90 or 100 kbps. Doing Shaw to Shaw drops to around 60 kbps. Speed tests outside of the tunnel shows good speeds both up and down. The good news is I have some interest from Shaw. Some techies have actually built two LRP gateways and are doing tests. They have found good throughput in the same city, but haven't yet put the second gateway in a more remote location to confirm my findings. My theory is based on their routers... the more involved in the route, the worse the results. I'd be interested in learning more about your routes etc if you wanted to contact me off-list.
