Yay!  It does sound like that might fix it.  (Admittedly it's a bit
beyond me.)

Yay!  Ok, I will do so.

Sounds good.  But here's a question: we haven't accepted many
contributions yet to 8sync.  Would it make sense now to require
copyright assignment for the project?  (We don't, yet.)  That might slow
development a bit but could make future merging into Guile, if such a
thing were to be done, easier.
