Hi there!
a) We are planning to release one or two more Betas later this year and get to production in Q1 2012. We are working on significant compatibility improvements of the system that we hope will allow virtually any web application to be compatible with HttpVPN with no changes to the application whatsoever.
b) We didn't decide on prices yet, but lean towards the following idea: consumers wound't have to pay anything for the first proxy, educational organizations and and non-profits would pay around $5/month subscription fee, business and government organizations would pay around $10/month. Please understand that the price is not final.
c) One proxy per LAN might be enough, depending on the traffic generated.
Please let is know if this information was helpful.
All the best,
UltiDev Team.
