		<description>Sounds great. Thanks for all your information and hard work. I am sure Rails 3 will be a huge success and the best framework out there. 
The idea of ActiveORM sounds very interesting. I think it would be great if Rails 3 users can switch between AR and datamapper if they choose to do so.</description>

		<description>@alex  Merb auth will certainly be migrated to Rails 3.0 like the other plugins.  The date/time select helpers is still something we are going to work on. Lori started working on something called ActiveORM which is an internal layer to make ORM agnosticism easier. Hopefully we will be able to leverage that to make better date/time helpers.</description>

		<description>Is there any plans to make things like MerbAuth and Authorization for rails3 like in Merb?
Is merb1.1 still alive? I would like to see date/time select helpers as described here http://merb.lighthouseapp.com/projects/7433/tickets/1093-add-a-date-selector-to-merb-helpers</description>

		<description>@Josh When we worked on Merb, we realized that there were few things we could do to significantly improve JRuby perfs. Here is a simple example from Yehuda&#039;s blog post on his recent work:

&quot;I did a lot of benchmarking on BlockAwareEnhancer. It turns out that for JRuby, the &lt;%= form_for %&gt;â€¦&lt;% end =%&gt; syntax  can bring down a page heavy with block helpers (1,000 block helpers to be precise) down from 30ms to 8ms. In MRI, the same technique brings the total time from 80ms to 65ms. (yes, that is a shockingly good result for JRubyâ€¦ seems like there are very common, expensive operations that JRuby kicks butt on).&quot;

We want to make sure Rails 3.0 runs as fast as possible on all the common implementations.</description>

		<description>&quot;Basically, the work started, we are getting familiar with the rails code base and are optimizing things slowly but surely with a focus on testing JRuby.&quot;

Why a focus on JRuby?</description>
