Resilin - Ultimate Rubber?

Just like with spider-silk, researchers seem to have found a way to make resilin, an elastic protein used by various insects:
http://news.bbc.co.uk/1/hi/health/4334908.stm
For medical applications(ie. artificial replacement arteries, etc), why hasn't elastin been used? Is resilin superior to elastin in its physical properties?
Where are the most promising industrial or non-medical applications? Just better basketballs and tennis balls? Or can it do tires too? (ie. does it have toughness, or just the elastic resilience?)
Since nanotubes are drawing away some of the interest in spider silk, will they do the same with resilin, or is there some other promising molecule that will do this?

Both are foreign proteins, which will be recognized and attacked by the immune system, therefore neither is suitable for implants in the human body.

Resilin is foreign, elastin is a human protein and conceivably could be used. How you make with the desired structure and attach it to the desired places are probably important problems with regard to using the material.
