[Catalyst] backbase.com's BXML GUI RIA could be a plugin for Catalyst App?

[=?GB2312?B?yqK0ug==?=]

Catalyst is a framework for web applications, it gives us a convient
envirentment
to write an application, normal as page-based application. And when
Catalyst::Plugin::Prototype
comes, the Ajax is giving another screen-based application. But the
page's XHTML or CSS
and Javascripts should write byself, some normal GUI like OS's windows
could not converient
build,the backbase.com gives some BXML and some lib to do that stuff.

for reference,

http://www.23hq.com/user/password-update?old%5fpassword=FFDD939AE&user%5fid=120043

That's an application which read from RSS and gives read in Ajax based page. It using Backbase's lib.

Catalyst well be more powerful if it native support or giving such stuffs, I think.
