[Opensim-users] toward a new client

Hello,

I just joined this list and saw that Gerco below said:

It's partially true, but I've recently got OpenSim running on a 64bit RedHat Enterprise server. The same would apply for a CentOS 5 server.

Some notes here:

http://learninglab.lincoln.ac.uk/wiki/OpenSim

If anyone wants me to go into more detail, please ask and I'll update the wiki.

I've a bunch of questions of my own, mainly client side, but I'll leave them for another post.

Cheers
Joss

On Linux: I hear ya :-)

It's just that a hosted VPS Linux is usually much cheaper than a Windows
server..
