[Opensim-dev] Unreal viewer: summoning the coders

[Rob Lindman]

If people are working on these viewers, especially on matters of URI 
handling... it would be nice if there was one (1) ONE with a decent 
gridinfo configuration panel. (Preferences -> Opensim -> Made Of Fail)

When attempting to add a test grid... It is exceptionally annoying if 
there is some difficulty in adding a new grid. You cannot manually edit 
the individual line items for grids in order to adjust the different 
pages. It frequently takes a while to fail if there is some difficulty 
reaching the /gridinfo file. I wind up with redundant 'lost continent of 
hippo' entries. I was trying to figure out what was going on testing on 
127.0.0.1 (which for some reason fails 'despite our best efforts'.)

The /gridinfo URI itself is also ridiculous. Check for /gridinfo.xml or 
something... I wanted 'mydomain.com' to be all a user had to put into 
this panel in order for it to work, instead of mydomain.com:9000 ... And 
so, hey, I am running apache, might as well just put a file up there 
called /gridinfo, that way I can omit the port number while fulfilling 
the /gridinfo requirements... While it was 'fun' to mess around with 
mod-rewrite... this whole process shows that the OpenSim / TPV community 
didn't put much thought into MAKING IT EASY for people to get on grids.

I ultimately had to open the Firestorm user grids xml file and add one 
in manually to access the opensim running on my local system. That's 
ridiculous. A typical end user is not going to want to go through that. 
I am an opensim / second life enthusiast and this hassle was enough for 
me to set the computer on fire. There is no easy way to debug what is 
happening here.

If I had to go through all this trouble every time I wanted to connect 
to A WEBSITE then I am sorry to say I would simply become Amish and 
start milking goats.

A replacement for LLUDP isn't needed. What's needed is for people to 
actually think about what they are doing. Try out the software under 
different conditions and wonder if a person new to this environment 
would REALLY want to contend with the seriously annoying issues that are 
basically in the way of anyone adopting OpenSim.
