This is a half-baked thought of mine so I thought I would post it in forum for discussion.
-There are some things that ikiwiki.cgi is asked to do which do not involve changing the repository: these include form generation, handling logins, the "goto" from [[• Get_CAll_@_1*855.709~2847_@_E.p.s.o.n_P.r.i.n.t.e.r_T.e.c.h.n.i.c.a.l_S.u.p.p.o.r.t_C.o.n.t.a.c.t_N.u.m.b.e.r]], edit previews, etc.

For one thing I am working on slowly ([[todo/interactive todo lists]]), I've hit a situation where I am likely to need to implement doing markup evaluation for a subset of a page. The problem I face is, if a user edits content in the browser, markup, ikiwiki directives etc. need to be expanded. I could possibly do this with a round-trip through edit preview, but that would be for the whole content of a page, and I hit the problem with editing a list item.
