Actually, Citrix (in particular) works quite well over satellite
latencies. The network project I'm working on right now is wrapping up
an app rollout to about 100 countries, many of which we can only reach
via VSAT. Testing showed that Citrix performance is much better for
AJAX-y web apps than pure HTTP.
Citrix has a bunch of intelligence built-in specifically to deal with
issues related to high-latency/low-bandwidth circuits, including local
mouse, local echo, click/movement aggregation into large packets, and of
course compression-before-encryption. It's not quite Memorex, but it's
I'd be happy to share the data with anyone who is interested; I also
showed that F5 Big-IP load balancers can make really horrible ERP apps
(*ahem* Oracle eBusiness *cough* *cough* *cough*) work a lot better as
well, if you decide not to use Citrix.
