Have you looked into Satelitte? Don't know if you have cable or are on satellite (for your TV), but this might be an option. The upsteams are pretty slow, but downstreams are fairly comparable to DSL. Just be aware, that the weather can, and most times will, affect your connection strength.

Probably not the best interim solution, but thought I would throw it out as a suggestion anyway.

Disclaimer: Under normal circumstances, I would never suggest satellite over cable or DSL, but desperate times call for desperate measures.
