SkyAngel has always piggybacked off of E* equipment ... so not having the features of E* receivers is not their concern. Moving to IPTV could actually add other features, such as a rewind (watch anything that was on in the past 48 hours). When you're doing one to one communications over the net you might as well stream what people want instead of what is on now.
If it is anything like other things that Dominion says (like having their own uplink center that they said that they would have ever since they started service) it may take longer than that. I also expect to see a "class action" (lawsuit) from "lifetime" subscribers who are no longer going to be able to get the service via satellite and will be required to pay for another receiver that might not have all the (DVR, two tuners) features that their current receiver has.
Not having broadband is the killer though ... that and asking "lifetime" subscribers to buy a $120 receiver plus $25 per month service (their Canadian rates). Perhaps when IPTV is released the rates will be better ... I doubt it.
There are "lifetime" subscribers who believe they got their money's worth ... but won't give another dime to the company. Unfortunately that applies to the satellite model as well. SkyAngel depends on people who support whether or not they are getting their money's worth.
One more interesting thought ... let a ViP-622 DVR or ViP-211 be a SkyAngel terminal. That would help, for those on E* with broadband.
