Actually, this is incorrect.
I know this thread is old, but there's some bad thinking in this country with regards to MMO's. SA is a small market (the entire continent of Africa even), which is the main reason we are not specifically targetted in any MMO marketing. It just doesn't make business sense.
They won't ever be hosted locally, but that does not mean we cannot play them.
Personally I've been playing MMO's for about 5 or 6 years now - all on overseas servers. I've played WoW/SWG/EQ/AC/UO and AO. The connections I've used have been 56k modems, ISDN 64k, ISDN 128k and Sentech. The lag I've gotten has not been that bad, except for when I was on Sentech. My lag using ISDN was in the 600 range, which is very playable and not even noticable. The vast majority of MMO's are designed to be latency tolerant to a degree (planetside may be the exception). It's not like playing Counterstrike or any of the FPS's.
A few friends of mine and I are big MMO players, have been for a long time. We're currently playing EQ2 and EVE Online, but are pretty keen to play WoW. Blizzard has introduced some measures recently that are designed to filter all EU players to the EU servers, and US players to the US servers. They have said that they are specifically using billing info as the mechanism, so if you do not have an american billing address, you cannot play on the US servers. However, we're working on ways to get around that. There's no word yet on if they're using IP filtering or not.
We discuss most of this stuff at
http://www.arcaneer.com/forum/ so stop by there in a week or 2 if you're interested in this stuff. We should have a definite answer on if we can play or not soon. We've got a pre-ordered copy of WoW on the way, so we'll see what happens.
Anyway, hope that clears up any misconceptions.
