[p2p-hackers] DHT or unstructured?

[Hailong Cai]

Hello, everybody

As we know, DHTs receive a lot of attention from academy while unstructured
systems thrive on the market.  I just want to know how these two types of
P2P would evolve in the near future, say, in the following 5 years.  Which
one will prevail and which one will die, or maybe they may merge into some
kind of hybrid system?  Could you please share your thoughts on this?
I don't know if this question has been asked before, but I want to know your
ideas at present.  

A.  DHT will succeed and unstructured systems will die
B.  Unstructured systems will continue growing and DHTs will fade away.
C.  They will merge into one.
D.  They will coexist but with different applications.  For example,
unstructured systems for file sharing, and DHTs for distributed storage
system. 
E.  Other


Thanks
