ALE ( Ajax Linking and Embedding) and ROR?

Hi,

This is a newbies question.
I am very impressed by Zimbra ALE ( Ajax Linking and Embedding) concept.
It is very cool and enable the mashup of disparate applications
altogether.

I don’t know if Ruby on Rails has this similar concept and
implementation.
If not it would be nice if the community push in this direction.

Any idea?

Thanks alot.

Regards,

Brice
