I use Skype, extensively for all communications to China and Far/Middle East. If Skype is not VoIP then I don't know what definition you could use. PS Skype over both SuSE and MS Win OSs (depends on computer)
Skype uses it's own underlying technology (peer to peer as far as I know). I'd consider REAL VoiP to be SIP (what Asterisk uses). Of course I'm not an expert on VoIP, the limit of my experience is getting an unlocked Vonage box working with Asterisk.
2. If any ISP uses BT wholesale, they cannot improve on the BT wire limit and in this village it is the age of the old 1960s cheap steel coated with copper in last cabinet to house wire that determines performance.
They can possibly improve on BT Retail's poor performance though. When I was briefly with BT it was an awful service, I was lucky to get 4 Meg (despite the fact the line was syncing at 7 Meg). My previous ISP Enta was giving me 7 Meg during the day (just wasn't as good in the evenings when I really wanted to use it).
3. I understand BT Retail is only a customer of BT wholesale/BT infrastructure but it is the infrastructure the wire/distance from exchange that is the limit irrespective of ISP.
If you're lucky to get ADSL2+ (either via an LLU operator or via BT) then chances are you might get a bit of a speed increase. The connection I'm using at the moment (not at home) is 2 Meg (BT IPStream Office I'm guessing), putting the number into a BT checker suggests with ADSL Max the line could handle about 3 Meg, but with Be LLU (ADSL2+) it suggests the line would support upto 6 Meg. Sods law Virgin is VERY close but don't run cable to the building (it's a commercial premises, not sure if it's possible to get Virgin to run cable to the building using their business service).
4. My speeds are adequate for all normal business needs. I am not a consumer of video/entertainment but do shift large CAD files to and from other countries.
I guess if you're shifting large CAD files across the world it'll still be quicker than posting them on CD/DVD :-)
