Facebook Apps All Over The Web

Thanks to AccuraCast I found that Facebook released JavaScript client library which allows Facebook developers to create applications which will work from any website. Should we think that this is next big step of Facebook expansion? I don’t know, but if I remember correctly developers had possibility to embed apps into websites before this release also, but with this JavaScript client library it is much more easy to do and, what is important, it does not require any server side coding.
