NB4.5/NBW: Orbis or Ibid for ethnographical research project

[David Mackinder <davemack>]

I have been asked by a friend to work as a research assistant. One of
the projects he has in mind is a piece of fieldwork centred on a
charismatic Christian group and involving participant observation and
interviews. Assuming that access is granted by the group's leaders, he
will do the fieldwork and I'll probably be responsible for transcribing
his audio cassettes and overall text management.
    I'm a long-time Nota Bene user, but I've previously used Ibid(em)
exclusively for bibliographical work and have barely used Orbis (save as
a contact manager).
    I know that there was a sample IbidPlus fieldnote database - how do
Notabenieri of a sociological/anthropological/ethnographical bent rate
this? Would it suffice? Or have you developed alternative templates
using either Ibid or Orbis?
    Alternatively, approaching this project from a non-NB direction, are
there other software tools that suitably experienced list members would
recommend? (I've got recent demos of Nudist and NVivo, and I've also
seen EZ-text.)
