Thin Client has been implemented in the NWS version of AWIPS2 since version
11.x for both Linux and Windows builds. It's described in Chapter 14 of the AUM
and Chapter 26 of the Combined SMM. Like most network programs, AWIPS2
performance depends on both latency and throughput of the link and so Thin
Client mode attempts to optimize these albeit at the cost of some loss of
functionality. In addition, AWIPS2 was designed to be have all configuration
data centrally controlled and dynamically updated but this means a lot of
round-trip client-server transactions for every action. The java serialization
of these transactions was also optimized for flexibility and not size/speed.
* The "Localization Caching" and "Map Caching" options disable checking for
new versions of this data and uses what's local. You may even pre-load all
localization data to the client which will speed CAVE startup considerably over
a slow link.
* Product data caching becomes more aggressive at the cost that partially
populated products may not be updated when complete.
* You can define a proxy server so both EDEX and Pypies use a single external
port (e.g. port 80 or port 443.) If you set this up as described, all
communications to/from the server will also utilize gzip compression (really
helps with some transactions, not so much for satellite images.)
* You can turn off the JMS push notification of new data and replace it with
timed updates.
Last I checked, Thin Client mode required AlertViz and CAVE to be started
separately (and with their respective '-component thin..." argument.)

I had read that NOAA and Unidata were separately working on developing a
AWIPS 2 Thin Client which would run under Windows and use remote
servers, but haven't seen any recent news regarding their efforts.
