I am tempted by OP's offer but I have to think about it. I have used it with Hotspot mode successfully from MiFi 2372, iPhone 4, and 2 diff. Android phones. So is that tethering? It depends on how you define "tethering", but basically most things work, and exception could be no difference than other officially paid data plans, so I don't think this plan makes it any less so. I haven't tested all VPN combo, so I can't say it's 100% exactly same as other Bell's plan, but so far I think it should be as it uses the Bell's Internet APN.
If OP's still looking then please send me a PM to discuss further. But honestly, I think OP's making a big gamble as no one knows when PC Mobile will pull this, as this is not an official plan usage.
