Pure Perl DateTime

Hi All,
  I'm new to this list so please forgive me if I'm talking about 
anything that have been previously covered.

I've been working on getting I18N into CGI::Application recently. I've 
got so far, but now I'm looking at working out the dates properly. It 
seems that this module is clearly the way to go but there is a big snag...

CGI::Application and Titanium aim to have the option of being pure perl, 
making it possible for developers to easily distribute all the required 
Perl modules along with the app.

I see that DateTime uses XS and do some of it's dependencies. As far as 
I can see from:-
http://deps.cpantesters.org/?module=DateTime&perl=5.10.0&os=any+OS&pureperl=on
DateTime
DateTime::Locale
Params::Validate
List::MoreUtils

Params::Validate isn't an issue as it's got a Pure Perl option. But the 
others certainly are.

So my questions are:-
Is there any effort currently being made towards having a Pure Perl option?
How hard would it be to have a Pure Perl option?

Thank you for your time
