We're currently investigating the feasibility, both technical and financial, of providing a button on the UI which causes a rendering to happen "on the cloud".  

We're pretty confident we can do about 320 core-hours of rendering overnight (10 hrs.?) for about $100.00.  That would be the equivalent of an 8-core machine working for 40 hours.  For example, four 10-hour renderings (80 cpu-hours each) would cost $25 each.  One 40-hour rendering would cost $100.

Large animations would be more and probably, at least at first, negotiated on a case-by-case basis.

Let me know what you think....
