Not crazy at all, especially if is a VM that can host multiple languages. Hm... What would be even more interesting is a VM that can be configured form the server. 1. User opens a page with scripts in LanguageX. The page links to some kind of VM configuration file. 2. Browser loads that file, which enables it to parse LanguageX. Browser caches that file. 3. From now on, the browser can execute scripts in LanguageX. Although, this particular idea might be the case when too much flexibility would lead to issues in the long run.
