How transferable is a Ruby on Rails CMS?


I am looking into a new website, and a couple of potential designers
have recommened using a CMS system built on Ruby on Rails ... one
bespoke and one using a customised version of Refinery.

Both have said that we will own all the coding, and so will in theory
have the flexibility to host the sites anywhere.

We are looking at hosting the site with a separate company, and I just
wondered if this would actually work - how well known is Ruby on Rails?
Would a different technical team actually be able to understand the CMS
to be able to provide support for it as they would with Drupal / CMS
Made Simple?


Shouldn't you be asking this "different technical team" such questions

Alternatively, pick your hosting company (or a maintaining developer)
based on ability to provide whatever you define as "support".
