This shows, that free as in beer, but not as in freedom, is a major road
block in the long run.

Unfortunately, the only way to fix this in a future secure way is to
actually reinvent the Wheels in an open source way.

This is a great step forward to make simulation within the geda context a
viable alternative to the less stubborn. A simulation suite desperately
needs a set of generic models of standard parts. Else, potential users
will turn elsewhere before they become users.
Of course, there are more essential ingredients to actually attract a
substantial user base. Next on the list is a workflow that is at least as
smooth and reliable like gschem->pcb->gerber. And of course, a complete
set of tutorial, examples, manual and in depth documentation.
Are there plans to achieve these essentials with gnucap, or ngspice? Is
an active developer working on it? Is there a road map?
