Well I'll probably be using Eligius and there's no option for adjusting difficulty. The internet at the apartment is pretty shitty (free, included in rent) so I don't wanna run into any troubles there.
Thanks guys
While the math is rather intensive, the bandwidth isn't. I can't recall where I saw the post, but someone had calculated that you could run close to ten TH/S on a 56k modem without ever really pushing it's limits. About the worst broadband available wouldn't be bothered by that.
I mine at Eligius, and the vardiff works well. I do occasionally have a noisy connection, and it will drop me down to diff 32 for a few minutes, but mostly it feeds at 64, and with almost no hiccups. When a block is found, I might get a reject or two, and that's it. I don't know where Eligius is physically hosted, but I'm pretty sure it's not anywhere close to Mountain Home, ID. (though it could be in Boise, conceivably. There's a lot of high tech there). Running at the speeds you're talking, I would imagine it'll set your diff around 256, so bandwidth should never be an issue.
