[esp-r] Sketchup plug in for ESP-r - is there one out there somewhere??

[Jon Hand]

I remember months or years ago there was a message about a Sketchup plugin for ESP-r
(probably a collection of Ruby code).

Anyone remember this?

Anyone know: 
a) where
 b)what it is
c) how to use it
d) where the source is?

If it exists - anyone interested in working on it so that there is another option for
interacting with ESP-r?
