I don't see anything that would prevent you from sending data all over
the globe, as long as you can get an IP connection to the remote site. I
don't know anybody who has done it, but it should be the same thing as a
local machine. You're actually the first one I hear about using OpenSG
for a collaborative app. I'd be interested in hearing about your
experiences here... ;)
As we don't do any compression on the data that is shipped the bandwidth
requirements would be pretty much the same as the structures in memory.
To get an idea of how much that is, you can just save your scene to a
binary OSG file, which is the same data that is sent over the network.
Note that the main idea of OpenSG networking is that only changes are
sent over the network, so this amount of data is only sent for the first
frame or whenever you change the geometry.
Hope it helps
Dirk
