Sopcast (and/or TVU and TVAnts) would be amazing to have on the N900. Excuse my ignorance but would the usual 350-500 odd kbps on sopcast streams (at least the ones I use) be conceivably doable over 3g, or would wifi be needed?

While typing that I just realised that watching one football match would put you over most provider's monthly fair usage policy for mobile internet but would still be interested to know if it is possible.
