Online Collaboration

We are in need of doing an online design collaboration (like a WebEx) with our location across the country.  The problem is our bandwidth isn't very good here.  We have tried in the past, but the speed was so bad that every time you would rotate a model, the graphics would lag way behind, and possibly even completely stop on the other end.

I was wondering if anyone may have any solution on how I can still make this happen, even with this limitation.  I didn't know if there was some type of remote service that would help us out with this problem.  Or really, any other solution that is reasonably feasible.  Unfortunately, improving the bandwidth is not an option.
