We currently offer web development in the following program languges.;
flash media server, red 5 media server, and wowza media server.
I've written a book covering coding video chat. You can buy the book from Amazon.com as a kindle book. Kindle Book Link The paper back is also available.Paper Back Link The book demo is currently using Flash Media Server Development edtion the amount of internet connection the demo uses is limited so exspect a slow demo.   A book receipt or a donation receipt grants you the right to use, modify, and redistribute my video chat application/source for personal or commercial purposes. The only restriction is the receipt must be in your name. Please direct questions at firstname.lastname@example.org
Future books I'm writing is a sci-fi book that takes place in a distant future. And another book about creating video confrence/chat using web-rtc its similar to the above mentioned book but has significant application performance increases.
I specialize in RIA 1 with emphasis on video chat applications, however we can use most program API2 which your application may require, we are just most comfortable with above mentioned program languages
