SMS is unreliable? Where?
Unreliable as in you get no guarantees if and when a message will actually be delivered. Try to find a carrier anywhere that offers you a contract with an SLA on SMS delivery. Granted, you won't often run into problems with SMS, but if you are bound by an SLA with a customer, you'd better have your underpinning contracts (yay for ITIL terminology) at the same level as that SLA.
In The Netherlands we also (used to? I emigrated quite some time ago) have such a copyright tax on many media
We still have that copyright tax on cassette tape, cd-rom and dvd-r, but not on mp3 players, flash cards or hardrives. BUMA/STEMRA is pushing for it, but for now the politicians have put the plans on hold. At least until BUMA/STEMRA can show what they are actually doing with the money they get from this scheme, as it becomes more and more clear that it's all just sitting in a savings account without the artists seeing a penny of it.
