My suggestion is to try and interest Gerald Evenden, the author of PROJ, in
resolving this problem.  If he prepares a patch for his libproj4 to support
RSO, then you an file a bug against PROJ.4 and encourage me and I'll port
the projection into the regular PROJ.4 which is used by MapGuide Open Source.

Gerald can be reached on the PROJ.4 email list.

I am obviously strongly in favor of having an open source solution to this
problem, but this might be a case where it makes sense to use MapGuide
Enterprise in the meantime.
