The World of Peer-to-Peer (P2P)/Building a P2P System/Developer

Developer edit

There are many reasons why one should invest time and effort in creating a P2P Application. As we already covered in the first chapter the P2P technology touches and has begun even to have impact in many fields of human endeavor. Besides the normal reasons behind any type of programming task (money, fame, and fun), it can also be an expression of a political stance or a vehicle to implement new concepts in networks or even economics. The bottom line is that P2P resumes itself to person-to-person, people working together for a specific goal. It is up to you, the programmer to create the infrastructure necessary to make this happen.

Any P2P project aims to become a widely used, trusted and reliable. Few are open, secure, free, non-discriminating, egalitarian, unfettered and censorship-resistant.

Selecting the Programming Language edit

To do:
RAD (prototype) vs resource use optimization


Selecting the License edit

Selecting the right license is the most important step for any software for public distribution. It will determine how the project will be done, even restrict the programming language that is selected to implement the solution, the time it takes to get to a final product and is of increasingly importance to the relation with the users.

There is a never ending list of licenses one can use out of the box and as the implementer you can even create your own. On this last step be very careful if you don't have a grasp on all the implications you shouldn't risk it.

The Open Source Initiative (OSI) offers a great an annotated definition of what Open Source is, here ( http://www.opensource.org/docs/osd ).

Open vs Closed Source edit

 

How can P2P generate revenue edit

 


 

To do:

Pushing content
Marketing(ads,...)
Monitoring and Control (know what your customers are searching for,control what they see)
Premium User list


Shareware / for Pay edit

This is the most problematic setup due to the legal hot-waters it can get you into and the formalisms and obligations that you need to comply to.

Also restricting the participation on the network will be intentionally reducing its usefulness, this is why most P2P services are free or at least support some level of free access.

Variations edit

There are several models that are variations of the simple donation/pay model, they give specific goals to the users or to the project in relation to the values collected.

Ransom
Put features or the code of the application up for a ransom payment, if people do contribute and fill that goal you accept to comply with your proposal (ie: opening the source code, fix or implement a feature).
Ransom has been shown to works in practice, it is used in several open source initiatives and even writers have tested this scheme, an example of the later is the test the writer Lawrence Watt-Evans has done on several titles, all successfully reached his monetary and production goal.
Pay for features
In a variation of the ransom model, in this particular case you should be extra careful to inform users on what they are paying for, and the legality of what you are providing for that payment. Extra feature may be better services or even a better quality for the existing ones.
Paid support
Paid support include providing users access to a paid prioritized service for technical support, this is very commonly use on Open Source projects. You should restrain yourself for over complicating the software so you can profit from it, as the users will be the network. One solution is to provide a default dumb down version for public consumption and enable a very high degree of tweaking of the software, protocol or network and then attempt to profit for it.

License new technology edit

In case you came up with a new technology or a way new interconnect existing ones that to can be made into revenue source.
