I thought I’d chime in that editing your template is going to be the easiest.
I tried iterating over the formsets in render_change_form but unfortunately, the major problem is that InlineAdminForms are constructed dynamically upon iteration in the template so you can’t just set inlineadminform.original = None or modify the context.
They don’t even exist until assigned a variable in the template.
# InlineAdminFormset
def __iter__(self):
for form, original in zip(self.formset.initial_forms, self.formset.get_queryset()):
yield InlineAdminForm(self.formset, form, self.fieldsets,
self.opts.prepopulated_fields, original, self.readonly_fields,
model_admin=self.model_admin)
and the only easily non-hackishly accessible hook we have there is overriding InlineAdminFormset.formset.get_queryset() which breaks other things.
Can I share some code nobody should ever really look at but works and makes me crack up laughing? I owe you one payne. Hope I can get to sleep tonight.

@sjaak-schilperoort Nice one! CSS is indeed the ‘trick’ to use. Example of the class Foo which has Bar as inline.
static/css/hide_admin_original.css:
td.original p {
visibility: hidden
}
.inline-group .tabular tr.has_original td {
padding-top: 5px;
}
admin.py:
class FooAdmin(admin.ModelAdmin):
inlines = [ BarInline, ]
class Media:
css = { "all" : ("css/hide_admin_original.css",) }
admin.site.register(Foo, FooAdmin)

I took a slightly different approach. It’s a little hackish. This replaces the “original” string with a blank string, so the td for class=original still gets rendered leaving a gap above the edit boxes.
I like the CSS solution better (I had to use ‘padding-top: 5px;’ to get the rendering right).
models.py:
class Model(model.Model):
general_questions = models.TextField()
_hide = False
def __unicode__(self):
if _hide:
return ''
admin.py:
class ModelInline(admin.TabularInline):
model = Model
extra = 0
class ModelAdmin(admin.ModelAdmin):
inlines = [ModelInline, ]
def render_change_form(self, request, context, *args, **kwargs):
for formset in context['inline_admin_formsets']:
qs = formset.formset.queryset
for model_obj in qs:
model_obj._hide = True
return super(ModelAdmin, self).render_change_form(request, context, *args, **kwargs)

In case anyone is looking to hide the header on a StackedInline, I used Rick´s approach but adding this css:
div.inline-related h3{
visibility: hidden;
height: 0;
}
