So, many of you could not be familiar with the event:
-DevHouse is a Hackathon with a party mood intended for people to share and learn. It started in Silicon Valley and has expanded Worldwide. It is a non-exlusive event were everyone can participate. Mexico is the first, and to my knowledge, the only latin-american country to host at least 1 SupperHappyDevHouse.

As of this specific instance it will be:
-This saturday from 10AM to 10PM local time.(GMT-6/Mexico City)
-It is expected for 500 people to attend.
-We are all looking for interesting stuff.
-I am going to lead on decentralization

So, basically, this thread is a throw all your ideas! I will print them several time at Friday noon so we don't run out of stuff. I am going to edit this post as Ideas pop on-topic.
-Decentralization
--Finances/Economics
---Bitcoin
----Wallet encryption
----Manage multiple wallets
----Easier addresses?(DNS)
----Automatically Rescan on wallet/s change/s.
----Close an address to avoid future incoming transactions in case of a wallet being compromised.
---Financial Institutions
----WOT for credit, insurance, and brokerage.(Similar to Ripple with a truly decentralized approach)
--Communications
---GSM Network(OpenBTS)
---Internet Infrasturcure(OpenMesh Project)
---BitDNS the only constraint right now is the "keep the blocks clean" vs "don't fragment the network"

Why decentralize? http://www.youtube.com/watch?v=RkmcupFx3FQ
So, feel free to suggest anything!
