Second that - labor-intensive but materials-cheap, no power tools and only a
few simple hand tools needed, etc. I've heard of using armature other than
metal (bamboo, plastic mesh, etc.) but don't know of any specific successful
projects to point to.

Great idea! Clay cheapest and most durable of course if you have the local
soil for it. Food grade liners are usually some $$$, unless somehow you can
get a deal (donations? Aid groups? etc.).

Absolutely.

These work great - used 'em myself - but they are
non-optimal/high-maintenance, especially if communal and/or
large/extended-family use. Examples on request...

For a community-use/large family situation I recommend lower-maintenance
double-vault type composting toilets - can be built using ferrocement, CMUs,
soil-cement block, local rock, rammed earth, etc..

This also keeps fecal matter out of other community compost piles, which *in
theory* is not an issue but in *practice*, if the practice is not perfect, can
be a very serious issue. I would expect this to be a bigger risk in Haiti
because a) it's in the tropics and b) I assume the general population is
carrying more critters inside 'em on average than most (for example) north
americans.
