you can install mono to a non-standard path and use that for opensim without
causing pain on the distro's mono setup.

if it's an easy, low-penalty work-around, yes and we've done that in the past.
however, there's the danger that we end up spending more time working around
mono bugs than we really want to.

for Sametime 3D we've done quite a bit of testing with the various mono
versions. we found that anything < 2.4.2 is just not stable (with the exception
of 2.0.1, but that suffers from performance/memory problems). your mileage might
vary, of course, in our experience we've crashed in the wall once we started
putting load on mono < 2.4.2.
