Ustinet includes Zope with its basic ($10/month) Web-hosting package. The
ColdFusion Developer's Journal carries ads for various site-hosting services that provide ColdFusion, with the cheapest advertised price being $15/month from
SiteHosting.net.
Is OpenACS hosting more expensive simply because it has so few customers, and therefore the sysadmins' work would be divided among a smaller group of people? Does maintaining an OpenACS site require substantially more sysadmin work per customer than maintaining a Zope or ColdFusion site? Or is $100/month simply the price that the market will bear at this point?
Obviously, the folks who provide this service have the right to charge whatever they want; I'm just curious about the economics here.
