No.

What we need is a decentralized exchange.

That is the problem.

Not more "solid players".  I know you meant well by saying that.  But truly:  Bitcoin needs no central points of weakness.

This is the entire reason it was created.  And are we shocked that the failures have been in the centralized elements? 

They are *always* the weak links in a decentralized network.

I don't know if Mastercoin Foundation's decentralized network invention is what I am referring to, but the days of "companies" owning "exchanges" and creating a "trust" situation needs to end.

More companies is not the solution.
