dSly: no idea. Back in the day (6000/7000/3000) Philips stopped shipping to Canada (from what I heard it was an RF issue (i.e. they did not bother getting it certified in Canada). Hopefully that has changed.
PS you might want to try asking Daniel Tonks. I have seen his name here once or twice, but he is a fellow Canadian and the owner of remotecentral. He has contacts in Philip and might know more.
I guess this opens up an answer to the otyher two questions.
jacket_fan, Waza04: it uses standard wifi and not propriatery RF like many remotes. Even with RF remotes (like the 3000,6000,3500,7000,7500 and European counterparts) RF is built to talk to a base that then transmits IR, some times you can luck out (Like the Prontots and X10) but there is never a guarantee that it will work in RF with an RF device, RF is propriatery and the only reason it worked on the Pronto was that they bought the RF from X10)
the nice thing about wifi is that it might work with other networked devices. They already added support for RadioRa and Escient
