In both the Barcamps at Hyderabad I found that there is one talk that clearly stands out clearly as my most favourite presentation in that barcamp. In Barcamp Hyderabad1 it was the talk by Jay Pullur, CEO of Pramati on what he thinks is the best opportunities in the web 2.0 space. In this Barcamp it was the talk by Farhaan, CTO Spokn where he spoke about a VoIP client that his company is developing specially for the mobile phone. The reason for my liking of these two is due to the fact that these guys understand the changes that are going in their respective space in an intuitive way. Also in their talk they explain these changes in plain & simplistic way for which I use a little bit of abstraction and models to explain.
Farhaan last when I knew was heading a company called Phonestack but looks like very recently he has started another company called Spokn which as Farhan describes is a company sitting out there so that it can eat telco’s for lunch. In his wonderfully articulate talk he explained about a new protocol that he designed called the Lightweight Telephone Protocol to make VoIP calls through a mobile phone. LTP is open source and is also going to be a part of Asterix in its next release. LTP is really light weight and the stack is written totally in about 2000 lines of C code and interestingly it does not have any dynamic memory allocation & thus no dangling pointer problems.
Apart from the size of the stack another thing that he mentioned was that LTP has presence designed inbuilt into it when compared to SIP stacks(it does not have inbuilt presence in it) which I think is really fantastic.
After the talk he showed me a nifty demo of the Spokn client running on a windows mobile OS phone. I have not been really able to toy around with the either the application or the stack but so don’t how well all of it works but from what he is described it is really poised great to take on the standards battle.
In a world of closed everything & low trust, openness is a strategic edge which is the card Spokn is seem to be playing.
If you are interested in tracking what is exciting that is going on in the web 2.0 & mobile 2.0 space in Hyderabad then I suggest you keep an eye on what Jay & Farhaan are doing 😀

Very Interesting. Sure would love to have a word with those guys sometime. Will try to get in touch.
the more i read about barcamps the more intrigued i am by them. is there a central repository available where one can access information on the content of these camps and connect with the people who participate in them? an organized database would be very useful, i think.
hi ,
the best place is barcamp.org where you can get all the details of the other barcamps but most of the discussions happen in various groups set up by people in different places. Unfortunately there is no single database, it is all very decentralized.
