As threatened promised, I have produced a renamed version of Ion3 that should avoid upstream trademark claims and thus be DFSG-compliant. Some translations are out-of-date, but I'll release a first version now and try to get those updated later. The new name is ParticleMan. When I put the name to a vote some time back the winner was Iceparticle, but there's already an icewm and I couldn't resist the TMBG reference. (Whoever suggested this name to me: I had already thought of it but forgot to include it in the poll.)

The packages are in my repository for now.
