Ive been watching this thread for some time, and its time for me to pipe
in...
I've been working on a viable hotel solution for some time now, and the
best I have been able to come up with is a terminal server with thin
clients (bootp, tftp, xdmcp... you know the drill) in the guest rooms.
The clients are NATed, due to cost of address allocation. They work fine
in this scenario, for the standard business traveler, as well as
providing universal access for everyone who does not carry a laptop. For
someone who wants more and has their own hardware, the terminal server
also routes v6 packets, providing end to end connectivity.
Regarding the ISP filtering issue, I had to figuratively kick my local
cable provider in the head to get them to drop the port 80 block on my
circuit, and they list all of their non-"business class" IP's with a RBL
in order to force usage of their mail relays.
Its a sad situation.

at least here in Germany Internet providers tend to
do and not to do what they want.
- Some cut off their clients every 24 hours (DSL)
This happens on the sub-IP layer and hasn't got to do much with ISPs.
- Some block or slowdown particular tcp ports
to get rid of peer-to-peer file sharing
You get what you pay for.
- Some redirect the first web access to any site
to their own to force you to read their ads
Same here.
- Very few support multicast. When I asked my
own provider, they didn't even know what this is.
(They said 'no, because they don't support Linux'.)
You can't get reliable multicast service anywhere in the world.
People tend to switch it off if it threatens to impact unicast
traffic. It's not possible to run production services over multicast
across the Internet at the moment, at least not without a fallback to
unicast.
- IPv6? Huh? What's that?
It's not a real problem to get native IPv6 over ADSL or SDSL.
- At least one large provider blocks port 25 to certain IP
addresses in order to force you to use the provider's
mail relay
Which one is that?
The case you are writing about does *not* block 25/TCP on the TCP/IP
layer.
It's true that certain extremely cheap products don't offer that much
Internet or Service. These products are marketed aggressively and are
usually sold at a loss. Nobody forces you to buy them.
