Thank-you for the reference John.

OSMP contains a set of SL-like building tools. Screenshots http://sourceforge.net/project/screenshots.php?group_id=112657
OSMP C# can be downloaded from http://sourceforge.net/project/showfiles.php?group_id=112657&package_id=198139
There is a proof of concept prim blender exporter/importer attached to this mail (are attachments allowed?). It imports core parameters, such as position and scale.

Regarding my comment on the blog, I was trying to stay technically
correct and not say it's impossible, but since there is a question of
the feasibility I'm going to go ahead and say it's "impossible". Even if
you were able to restrict all of the SketchUp tools down to the bare
basics, 1) you wouldn't be able to use most of the functionality of
prims because the way the Second Life engine handles cuts, hollows,
twists, etc. is very unique to it's own engine and would need to be
mimicked in whatever target platform you're looking at. And 2) SketchUp
would still use it's own format for storing things which is a completely
different line of thinking from how SL looks at objects. My guess is
that the best building tools will be a standalone program written from
the ground up, there's already C# code in the open source metaverse
project to faithfully render prim.blender format xml files in to
something like you'd see in SL, we just need some building tools added
on. Again much easier said than done but that would be worlds easier
than trying to support SketchUp, to put things in perspective.

I could fix it on our end, but the current version of prim.blender
writes them uppercase and other possible utilities might follow suit, so
you'd have to plan for the worst case scenario anyways.
