[Opensim-dev] Any way for the server to get the viewer to send some information to another process on the client PC?

[Dahlia Trimble]

I've used gridproxy (part of libomv -
http://lib.openmetaverse.org/wiki/Main_Page ) to interface to other
processes without modifying the LL viewer by writing a *gridproxy
plugin*which is basically a small c# program in the form of a dll
file. I believe
there are some examples that come with libomv. Gridproxy monitors traffic
between the server and the  viewer and allows messages to be modified and
injected into the traffic stream. It's probably not the most user-friendly
way to accomplish what you want but it could be packaged into a fairly
simple to use program.

Another method I've seen is to set up a process that monitors the chat/IM
log files that the viewer can create. I've seen this method used fairly
successfully for adding accessability features such as chat text-to-speech
for visually impaired users.

Good luck with whatever path you choose :)
