Unfortunately scsh has a non-GPL compatible license (in fact, one that
I believe would not meet DFSG/OSD), so either the Scheme bits of scsh
must be reimplemented entirely to tightly integrate them with guile,
instead of porting, or relief must be sought from the
authors. However, it would indeed be nice if someone would update and
maintain the existing port.
