the answer is unfortunately IT DEPENDS....on the customer's level of knowledge, their budget, the ISP's budget, their technical support, their sales guys level of 'greed', the market, the regulator etc etc...I could write on and on....in the case of VOIP, it depends on the codec, regulation, the VOIP service provider,how 'connected are you? the protocols involved...I mean the variations are endless....however if you know EXACTLY what you're looking for then you get an ISP that satisfies THAT specific need, which is what whoever started this thread did, If all you go and ask for is a connection, TO the INTERNET, then the only bit of the link you can be guaranteed is the local loop, and the ISP really can't be blamed now can they...I also think using you tube as a focal point is a bad idea..........we could make a long debate out of this....there's just no free lunch ..anywhere...ISP's are running a business, customers are looking to maximize on what they paid for its just the way it is, this model could change dfrastically if the internet users became more cluefull of their needs... if you need further discussion on this, please unicast me with specific questions..i might be able to assist...

During the VSAT days :
SCPC (single channel per carrier) is a long used and proven technology which stands out for it's high reliability, bandwidth efficiency and flexibility. Separate channels are used for both uplink / downlink each being assigned a unique frequency. You will be able to define your uplink and downlink bandwidth at your own will in order to take the best out of the service.
SCPC service suits best:
Corporations Medium size enterprises Hotels ISPs
Then there this :
SCPC / DVB : Means SCPC uplink, return via DVB.
All uplinks are more expensive than downlinks, except in SCPC case.
Then this eg :
Services are delivered from the powerful Eutelsat W1, Telstar 12, Eutelsat W5, Sesat 2, Hellasat-2, Newskies (NSS6 , NSS7 ) and Eutelsat W3A satellites, respectively, in C-band , Ku band and Ka band, respectively, to ensure highest service reliability (99.95% service uptime guaranteed) in the challenging weather conditions of covered countries.
What is important is criteria of service. Infact, most serious VSAT operators will even tell you the estimated max number of computers that the service is recommended on.
I'm sure there are many gurus on the list who can add.
