Well, even with high bandwidth video conferencing, I don't think the job could be done very well at a distance. Failing to convince Larian to move to your location, if you want a game developer job your most practical options are to be prepared to move or find a closer game company.
I know there may be personal reasons to not want (or be able) to move, and there are tax implications and lots of paperwork (passports, work visas, etc) involved with working in another country, but it is certainly not impossible to do. I'm kind of tempted to look into that myself...
