Do you think that there is enough interest and potential
speakers for a minisymposium on Maxima?

SIAM, the society for industrial and applied math,
has, at various times, been a more plausible host
for applications of computers to symbolic math than
(say) ISSAC conferences which have been hijacked
by theorists, and usually have very little relevance
to applications or systems.
Anyway, I suggest you check it out. The meeting is
in New Orleans (USA) in July. There is an organizer
deadline in 8 days.
