I work in the app / WAN optimisation space, and periodically do some work with SCPS -- I'm guessing you're referring to the tweaks around buffers / BDP, aggressiveness around error recovery and congestion response? I think there'll be a few answers to the problem - first, it'll be slow to impact many of the kinds of users currently using Satellite, second for web apps it's either internal (so they can define transport) or external (in which case they are, or can, use a proxy and continue tcp/http over the sat links. Later on I expect we'll get gateways (in the traditional sense) to sit near the dish ... though I also would expect that on that timeframe you'll be seeing improvements in application delivery. Ultimately I hope - hubris, perhaps - that the underlying problem (most of our current application performance issues are because apps have been written by people that either don't understand networks, or have a very specific, narrow set of expectations) will be resolved. (Wrangling CIFS over satellite - f.e.)
